1 mol = 6.02 x 10^23
2.88 x 1023 atoms = 2946.24 atoms = (2946.24) / (6.023 x 10^23) moles
= 4.89 x 10^-21moles
Or if you meant=> 2.88 x 10^23 atoms = (2.88/6.02) moles = 0.478 moles (3 s.f)

How many atoms are in 3.50 g of gold?
1 mole of gold is 196.97 grams. 7.2 mol Au * (196.97 g Au/1 mol Au) = 1418.18 g There are 1418.18 grams in 7.2 moles of gold.
How many moles are there in 2.61 x 1024 atoms of gold?
2.61 X 10^24 atoms of gold (1 mole Au/6.022 X 10^23) = 4.33 moles of gold
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
How many grams of gold are there in 15.3 moles of Au?
If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.

How many moles make up 20.00 atoms of Au?
For this you don't need to have the atomic mass. Take the number of atoms and divide it by Avogadro's constant, 6.02 × 1023. Multiply by one mole for units to cancel.20.00 atoms Au / (6.02 × 1023 atoms) = 3.32 × 10-23 moles of Au
How many atoms are in 3.50 g of gold?
1 mole of gold is 196.97 grams. 7.2 mol Au * (196.97 g Au/1 mol Au) = 1418.18 g There are 1418.18 grams in 7.2 moles of gold.

5.6 moles of gold contain how many atoms?
5.0 grams gold (1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au) = 1.5 X 1022 atoms of gold ===================
How many grams of gold are there in 15.3 moles of Au?
If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.
The number of Au atoms in 1.5g of Au is?
n(Au)= 1.5g/M(Au)= 1.5/196.97 = 0.00761537mol n(Au) = No(Atoms)/N(a)therefore N(Atoms)=n(Au) x N(a)N(atoms) = 0.00761537mol x 6.02x10^23mol*-1N(atoms) approximatly equals 4.6x10^21 atoms
