I need to find the mass of 1.1 x 10^23 gold atoms. How would I do it? Thanks!?

If you have one mole of atoms, their mass is equal to their atomic mass in grams. "One mole" just means 6.022x10^23 (Avogadro's number) of something - "mole" is just a number of things, like "dozen" or "gross". The atomic mass of gold is 196.97 amu, so the mass of 6.022x10^23 atoms of gold is 196.97 g. Use this as your conversion factor:

1.1x10^23 Au atoms | 196.97 g / 6.022x10^23 Au atoms | = 35.98 g

1 mole of gold contains 6.022 × 10²³ gold atoms.
No. of moles of gold = (1.1 × 10²³ gold atoms) / (6.022 × 10²³ gold atoms/mol) = 1.1/6.022 mol

Molar mass of gold = 197.0 g/mol
Mass of gold = (1.1/6.022 mol) × (197.0 g/mol) = 36 g
