What does the mark 100 on silver mean?
The production of silverplated cutlery on an industrial level began in Germany in the middle of the 19th century. Two factors limited the output:1. Access to electrical power was very limited at the time.2. Electrical current was quite weak compared to the present day.After some experimenting, engineers achieved the best results if they used a small bath, put one dozen table spoons and one dozen table forks in it, used 90 Grams of fine silver and then immersed the pieces until the silver anodes were dissolved and the silver had firmly settled on the cutlery. This took many hours and in the beginning made the finished pieces quite expensive. The engineers discovered that a little more than half of the 90 Grams used was spread on the 12 spoons (as they have a bigger surface than the forks), a little less than half was spread on the 12 forks. Using a larger bath would require a much longer plating process, which would have made the process even more expensive. To use more than the 12 + 12 pieces in a bath would result in:1. The pieces closest to the silver anodes would get a much thicker plating.2. The pieces farthest from the anodes would get a very thin plating.So the thickness of the silver layer would differ considerably.Using 12 + 12 pieces as described above and 90 Grams of fine silver became a standard in Germany. To document this, the "90" was punched on the pieces. If companies wanted to produce cheaper cutlery, they used less silver, 60 Grams, 40 Grams or even 20 Grams, which made the plating very thin. Some used more, 100 or 150 Grams. Pieces were punched accordingly "60", "40", "20", "100" etc.The plating process was adapted to other pieces of flatware and cutlery; knife-handles, smaller spoons, serving pieces etc., so that the silver layer on them was as thick as on the table spoons and table forks. As the same standard process was used, they all were stamped with the "90". New techniques made it possible to plate more pieces in bigger baths in shorter time, using much larger silver anodes. However, the thickness of the plating remained the same , so the marks remained the same.When plated cutlery became more affordable and more and more customers bought it, they began to ask how much pure silver their flatware actually "contained". Manufacturers realized that they could use the answer as a method to promote sales and started punching a further mark that roughly provided the actual gram weight of the silver that coated the pieces. Unfortunately they used two different systems:1. Pieces that usually come in a dozen (table- forks /-spoons / -knives, coffeespoons etc.) are punched with the weight of silver used for plating a dozen pieces. So tableforks and tablespoons were marked with a "45", smaller pieces were punched a lower figure (e.g. "35"), as less silver was needed to give them the same thickness of plating.2. Pieces that usually came singly or in pairs (serving pieces) were punched with the weight of silver on a single piece.Examples:If you have a table spoon marked "90" and "45" it means: the standard process as described above was used, on one spoon roughly 1/12 of 45 Grams(ca. 3,75 Grams) of fine silver were spread. If you have a sugar tong marked "90" and "2" it means: again the standard process was used, 2 Grams of fine silver were used to coat the piece. If you have a pair of salad servers, each piece marked "90" and "4" it means: again the standard process was used, on each piece 4 Grams of fine silver were used.This German system of silverplate marking has been adopted by other European countries, and is sometimes seen on Dutch, Danish and Austrian silverplate.
What is the mass of a mosquito in scientific notation?
In the SI (metric) system mass is about 3 milligrams or 0.003 grams or 3 times 10 to the negative 3 power in scientific notation. In the US system mass (weight) is 0.0000066 pounds or 6.6 times 10 to the negative 6 power in scientific notation.
What is A to the second power plus a to the second power?
2a to the second power. If you combine the like terms, (a to the second power + a to the second power), it would be the same as 2a to the second power.
What are the 5 types of power ssd1?
The United States Army has five types of power for the SSD1. These five types of power include legal power, reward power, coercive power, referent power, and expert power. These powers are earned through achievements.
What is a power in maths terms?
a power is a power
What is the mass of 5.44 x 10 to the 25 power atoms of silver?
By definition, Avogadro's Number, about 6.022 X 1023, for an element is the number of atoms in one gram atomic mass. The gram atomic mass of silver is 107.868. Therefore, the mass of 5.44 X 1025 atoms of silver is [(5.44 X 1025)/(6.022 X 1023)] X 107.868 or 974 grams, to the justified number of significant digits.
What is the mass of 3.30 x 10 to the 23 power of atoms of silver?
107.8682
How many grams are there in 7.97 x 10 to the 24 power atoms of calcium?
7.97 X 10^24 atoms Ca (1 mole Ca/6.022 X 10^23)(40.08 grams/1 mole Ca) = 530 grams of calcium
How many atom are in 143g of calcium?
First, look up the atomic mass of calcium: 40.08 grams per mole 143 grams, divided by 40.08 grams per mole, results in 3.57 moles. Since you specifically asked for the number of ATOMS, multiply by Avogadro's number, 6.02 x 10-to-the-23rd-power atoms per mole. Final answer: 2.15 x 10-to-the-24th power atoms.
What is mass in grams of 1x10 power 20 atoms of NA?
1mol Na in grams = 22.989770g 1mol Na atoms = 6.022 x 1023 atoms 1 x 1020 atoms Na x 1mol/6.022 x 1023 atoms x 22.989770g/mol = 0.004g Na (rounded to one significant figure)
How many atoms are in 1.008 grams of hydrogen?
hydrogen is H2, with a molecuar weight of 2.016. In 1.008 grams of H2 there are 3.011 X 10 raised to power 23 (approx) 2.011 X 1023 molecules or 6.022 X 1023 atoms. Ovviously you can go straight to the answer as the weight is the atomic mass in grams.
How many atoms are found in 600 grams of iron?
To find the number of atoms we need to find number of moles of Fe in 312.0 grams. Molar weight of Fe = 56 Number of moles of Fe in 312 grams = 312/56 =5.571 moles. 1 mole of Fe has Avogadro number of atoms. So 5.571 moles of Fe has atoms = 5.571 * Avogadro number. Avogadro number = 6.022 * 10^23 So total atoms = 5.571 * 6.022 * 10^23 = 33.548 * 10^23 * means multiply, ^ means raised to power.
How many moles of silver (Ag) are present in a sample of 3.8 10 to the power of twenty four atoms Ag?

How many atoms in 12 grams of carbon?
Atomic mass of carbon: 12.0 grams12.01 grams C × (6.02 × 1023 atoms) / (12.0 grams) = 6.03 × 1023 atoms of CarbonNote that one mole of any substance is Avogadro's constant (6.02 × 1023) and that one mole of Carbon is 12.0 grams. So if you have 12.01 grams of carbon (roughly one mole) you should get about Avogadro's constant.

Explain Will kg of hydrogen contain more atoms than kg of lead?
Since,1 gram of hydrogen contains= 6.02*10 raise to power 23therefore, 1000 grams of hydrogen contains = 6.02*10raise to power 23 * 1000 i.e 6.02*10raise to power 26!!nd 207 grams of lead contains=6.02*10 raise to power 23therefore 1 gram of lead contains= 6.02*10 raise to power 23 / 207hence .. 1000 grams of lead contais= 6.02 * 10raise to power 23 * 1000 / 207= 29.08 * 10 raise to power 23Hence we can say tht hydogen contains more no. of atoms !!
