First you have to convert mmol to mol,

0.0102/1000=1.02*10^-5 mol.

Second, multiply the mol by avogadro's number (6.022*10^23)

(1.02*10^-5)*(6.022*10^23)=6.14244*10^18

Third and last, Round to 3 sig figs

6.14*10^18

Amount of gold = 10.0/197.0 = 0.0508mol

1 mol of Au contains 6.02 x 1023 atoms (avogadro constant).

Therefore 0.0508mol of Au contains 0.0508 x 6.02 x 1023 = 3.06 x 1022 atoms.

How do you do mass to particles?

By particles, I assume you mean atoms. Firstly, you divide mass by molecular mass to get moles. Then multiply moles by avagadros number to get amount of atoms

How many atoms are in a gold ring that has a mass of 19.7 grams?

Well, firstly you need to know if it is pure gold. Assuming that it is, convert the grams to moles 19.7g Au x 1molAu/197.0gAu = 0.1moles Au And then, to get the number of atoms in 0.1 moles of gold, multiply it by Avogadro's number, 6.22x10^23 atoms per mole 0.1mol Au x 6.22x10^23atoms/mole = 6.22x10^22
