A platinum bar measures 5 cm long 4 cm wide and 1.5 cm thick It has a mass of 700 grams What is the density?
Density is calculated by dividing the mass of an object by its volume. The volume of the platinum bar can be calculated by multiplying its length, width, and thickness. In this case, the volume would be 5 cm x 4 cm x 1.5 cm = 30 cm³. Therefore, the density of the platinum bar would be 700 grams / 30 cm³ = 23.33 grams/cm³.
What will happen to a density of a gold bar that is 15cm x 7cm x 5cm when it is rolled into a sheet that is 25cm x 42cm x 0.5cm?
The volume of the gold bar is not affected by such a physical deformation and remains at 525 cm3 and so the density is unchanged.
What is the mass of a bar of aluminum measuring 1.0 cm by 1.0 cm by 10.0 cm?
Well, isn't that just a happy little question! To find the mass of the aluminum bar, we can use the formula Mass = Density x Volume. The density of aluminum is about 2.7 g/cm³, so we can calculate the volume of the bar (1.0 cm x 1.0 cm x 10.0 cm) and then multiply it by the density to find the mass. Remember, there are no mistakes, just happy little accidents in math!
What is the total mass of three gold bars that weigh 5543 mg and 697.4 mg?
OK, we have you surrounded now! Where is the third gold bar?
What is density of the smaller block of goldin grams per cubic centimeter?
From here, I can't quite make out the blocks of gold that you're looking at.But the density of gold is about 19.3 gm/cm3 , whether it happens to be a flake,a nugget, a coin, a bar, or an ingot. With density, size does not matter.
A shiny gold-colored bar of metal weighing 57.3g has a volume 4.7 cm3 Is the bar of metal pure gold?
The density of the shiny, gold-colored bar of metal is 12.19 grams over cubic centimeters. The density of a Gold(Au) is 19.3 grams over cubic centimeters. These means that the gold-colored bar of metal is not pure gold.
What is the volume of a 25-kg 24-karat gold bar OF 999.99 fineness?
To calculate the volume of the gold bar, we first need the density of gold. The density of gold is approximately 19,320 kg/m^3. Using this value, we can calculate the volume of the gold bar by dividing the mass of the bar (25 kg) by the density of gold. This would give us the volume of the gold bar in cubic meters.
What is an example of Density equals D Mass equals M Volume equals V and D equals mass of object over volume of object?
An example of the density equation would be calculating the density of a gold bar. If the mass of the gold bar is 100 grams and the volume is 20 cubic centimeters, you would divide the mass (100g) by the volume (20 cm^3) to get a density of 5 g/cm^3.
If a 68-g bar of gold is cut into 3 equal pieces how does the density of each piece compare to the density of the original gold bar?
The density of each piece remains the same as the density of the original gold bar. Density is a characteristic property of a material and does not change with size or shape. Thus, each new piece will have the same density as the original gold bar.
A 68-g bar of gold is cut into 3 equal pieces how does the density of each piece compare to the density of the original gold bar?
Exactly the same.
Compared to a bar of pure gold what is the density of a pure gold ring?
The density of a pure gold ring would be slightly lower than a bar of pure gold because pure gold rings often contain other metals like copper or silver in their alloy. The addition of these metals decreases the overall density of the ring compared to pure gold.
How could you use density to determined whether a bar of metal is pure gold?
You could compare the measured density of the bar of metal to the known density of pure gold (19.32 g/cm³). If the measured density matches the density of pure gold, there is a high likelihood that the bar is made of pure gold. If the measured density is significantly different, then the bar is likely not pure gold.
How many atoms of gold are in the bar?
The number of atoms in a bar of gold depends on the mass of the bar. To calculate the number of atoms, you would need to know the mass of the bar and the atomic mass of gold. You can use Avogadro's number to convert from grams to atoms.
What is the mass of a gold bar 30 cm x 10 cm x 10 cm if the density of gold is 19.3 g per cubic centimeter?
To calculate the mass of the gold bar, you first need to find its volume. The volume of the gold bar is 30 cm x 10 cm x 10 cm = 3000 cubic cm. Next, you multiply the volume by the density of gold (19.3 g/cm³) to find the mass. Therefore, the mass of the gold bar would be 3000 cm³ x 19.3 g/cm³ = 57,900 grams.
Would a 1 kg bar of gold have the same density on Mars as it does on earth?
If you use the definition of "density" as mass/volume, then yes. That's the standard definition.However, it is also possible to define density as weight/volume.
How does volume of a chocolate bar affect the density?
Density is equal to M/V. So, if the volume of the chocolate bar increases, the density decreases, and if the volume of the chocolate bar decreases, the density increases. This is called an inverse relation.
How is volume and mass extensive?
Intensive properties depend only on the type of matter you're dealing with. For example, density: a single atom of gold will have the same density as a huge bar of gold, it doesn't matter how much of it there is. Extensive properties do depend on how much of the substance you have. A cubic centimeter of gold has more volume and mass than an atom of gold, so they are both extensive properties.
