Answer:

Explanation:

Every periodic table is rounded differently. My numbers will be approximate.

mols = 0.6 grams/ 40 grams / mol         40 is the number you need to get from the periodic table.

mols = 0.015

1 mol of anything is 6.02 * 10^23

So the formula you should use is atoms = 0.015 * 6.02 * 10^23

Answer: 9.03 * 10^21
