There are 1.65 * 10^ (-7) g S in 3.01 * 10^15 atoms S.

Step 1. Use Avogadro's number to convert atoms of S to moles of S

Moles of S = 3.01 * 10^15 atoms S * (1 mol S/6.022 * 10^23 atoms S)

= 5.148 * 10^ (-9) mol S

Step 2. Use the molar mass of S to convert moles of S to grams of S

Mass of S = 5.148 * 10^ (-9) mol S * (32.06 g S/1 mol S) = 1.65 * 10^ (-7) g S
