What is the density of a substance that has a mass of 54 grams and a volume of 3centimeters to the 3rd power?
This is simple math. Density=Mass(grams)/Volume(milliliters) so since 3^3=27 then it works out to a simple D=54/27 aka 2. 2kg/L to be exact.
How many copper atoms are in a pure copper statue with a mass of 129 kg?
The atomic weight of copper is 63.546 grams per mole. 129 kg is equal to 129000 grams. So there are 2030.03 moles of copper. There are 6.022 x 10^23 copper atoms in a mole. So there are 12.22 x 10^26 atoms.
How many milligrams are there in 27 grams?
There are 1000 milligrams in one gram. Therefore, 27 grams is equal to 27 x 1000 = 27000 milligrams.
What is 27 rounded to the nearest whole gram?
It is 27 grams.
What is the approximate density of the cube if each side was 3cm and the mass is 12g?
Density = mas/volume = 12 g/27 cc = 0.44... recurring grams per cubic centimetre.
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
What is the number of moles in 54 grams of aluminum?
To calculate the number of moles in 54 grams of aluminum, you need to know the molar mass of aluminum, which is 27 g/mol. Divide the given mass by the molar mass to get the number of moles: 54 g / 27 g/mol = 2 moles of aluminum.
If 40 grams of sodium hydroxide and 3 grams of hydrogen gas are produced when 27 grams of sodium metal is consumed how many grams of liquid water must have been added?
Using stoichiometry, we can calculate that 27 grams of sodium metal reacting with water produces 40 grams of sodium hydroxide. Since 40 grams of sodium hydroxide were produced, this correlates to 27 grams of sodium being consumed. Therefore, the water added should be the difference between the initial weight of sodium (27 grams) and the weight of sodium left (0 grams) after the reaction, resulting in 27 grams of water being added.
What is the density of a block of aluminum that has mass 27 grams of and a volume 10 cubic cm?
The density is the mass per unit volume. So, the density = 27/10 = 2.7 grams/cc
The Earth has a radius of 4000 miles.One cubic meter of rock has an average mass of 5 metric tons. What is the mass of the Earth in grams?
6.705909598079999e+27 grams
How to convert 1.5 mol of water into grams?
To convert 1.5 mol of water into grams, you can use the molar mass of water, which is approximately 18.015 g/mol. Multiply 1.5 mol by the molar mass to get the grams of water. Therefore, 1.5 mol of water is equal to 27.02 grams.
How many tablespoons is in 27 grams?
27 gm of water is about 1.9 tbsp
How many grams is 27 grams of cannabis?
27 grams of cannabis is equal to...27 grams.
How do we measure protons in grams?
The mass of 1 proton is 1.6726219 × 10-27 kilograms
Mass of the earth in grams?
Go to the Wikipedia, and look up the mass in kilograms. Then multiply that by 1000 to convert to grams. (Since you will find the number in scientific notation, this means adding 3 to the exponent.)
What is the mass in grams of 1.00 mol Al?
The molar mass of aluminum (Al) is 26.98 g/mol. Therefore, the mass of 1.00 mol of aluminum is 26.98 grams.
A substance has a mass of 27 grams and a volume of 10 cubic centermeter its denstity is what?
Not sure that anything has a volume of a cubic centremeter, since there is no such measure. Cubic centimetre, yes. Density = Mass/Volume = 27 g / 10 cc = 2.7 grams per centimetre.
