Does a mole of carbon atoms have a different mass than a mole of Sulphur atoms?
Difficulty: Easy
One-mole quantities of two different substances have different masses.
If we put one mole of carbon and one mole of Sulphur on separate balances, we would see a difference in mass. This occurs because carbon atoms differ from Sulphur atoms. Thus, the mass of 6.02 x 1023 carbon atoms does not equal the mass of 6.02 x 1023 Sulphur atoms.
