Au contains how many gold atoms?
This depends on the mass of the gold sample.
What mass of gold contains twice as many atoms as 2.74g of silver?
The gram atomic mass of silver is 107.868 and that of gold is 196.967. Equal numbers of gram atoms of different elements contain equal numbers of atoms. Therefore, the mass of gold required to contain twice as many atoms as 2.74 g of gold is (2 X 2.74 X 196.967)/107.868 or 10.0 g of gold, to the justified number of significant digits.
How many atoms of gold are in 5 grams of gold?
Atomic mass of Ag: 107.9 grams5.00 grams × (6.02 × 1023 atoms) / (107.9 grams) = 2.79 × 1022 atoms Ag
What mass of gold contains the same number of atoms as 9.00g of Aluminum?

A sample of gold has a mass of 5.00 x 10-3g. what amount of gold in atoms does the sample contain?
5x10-3 g divided by m.wt. of gold (197 g/mol) equals 2.5x10-5 mol gold.2.5x10-5 mol gold multiplied by Avogadro's Number (6.023x10+23 atoms/mol) equals 1.5x10+20 atoms.

How many atoms does 100 grams of gold have?
Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.

What explains the difference between the mass of gold and the mass of water?
Protons and Neutrons in the nucleus, also, water is a covalently bonded substance, whereas gold is a metallic structure of gold atoms.

In Rutherfords gold foil experiment some of the aimed at gold atoms bounced back suggesting that a solid mass was at the center of the atom?
In Rutherford's gold foil experiment, some of the Alpha particles aimed at gold atoms bounced back, suggesting that a solid mass was at the center of the atom.They suggested that most of the mass of the atom is concentrated at the center and the center is positively charged.

5x10-3 g divided by m.wt. of gold (197 g/mol) equals 2.5x10-5 mol gold.2.5x10-5 mol gold multiplied by Avogadro's Number (6.023x10+23 atoms/mol) equals 1.5x10+20 atoms.
How many atoms are in 175 g of calcium?
175 g Ca (1 mol / 40.078 g) (6.022x10^23 atoms / 1 mol) = 2.63x10^24 Ca atoms There are 2.63x10^24 c.alcium atoms in 175 grams of calcium.
Is Density is the measurement of the number of atoms or molecules in a given volume?
Density is the relationship between mass and volume. the number of molecules in a given mass is molarity. -------------------------------------------------- No it is not. Because atoms come with different masses, so you could have 1 billion atoms of hydrogen occupying the same volume as 1 billion atoms of gold but the gold would weigh more than the hydrogen.
