Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.
molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g
A mole of Au
The gram atomic mass of titanium is 47.867. Therefore, in a 0.65 mole sample, there will be 0.65 X 47.867) = 31 grams, to the justified number of significant digits.

Lead. The molar mass of lead is 207.2 g/mol while helium's is 4.0 g/mol.
This value is 207,2 g.
Mole times Lead's Molecular mass(Mr) gives you its mass And I think the Mr of Lead is 207

Chlorine is non metal element. Atomic mass of it is 35.
just divide the mass of sample by the mass of argon. OR: atomic mass of argon is 40 g/mol, so in a 40g sample of argon, there ought to be 1 mole atoms, or 6.02x10^23 atoms
Silicon carbide has the formula SiC. The mass of 1 mole would be 28 + 12 = 40 g/mole
