Answer:

Explanation:

1 mol of anything is 6.02 * 10^23 atoms (in this case)

x mol of 3.01 * 10^22

Set up the proportion

1/x = 6.02*10^23 / 3.01 * 10^22                 Cross multiply

x*6.02 * 10^23 = 1 * 3.01 * 10^22               Divide by 6.02*10^23

x = 3.01 * 10^22 / 6.02*10^23

x = 1/(2 * 10)

x = 1/20 mol

x = 0.05 mol
