There are 1.65 × 10^(-7) g S in 3.01 × 10^15 atoms S.
<em>Step 1</em>. Use Avogadro’s number to convert <em>atoms of S to moles of S</em>
Moles of S = 3.01 × 10^15 atoms S × (1 mol S/6.022 × 10^23 atoms S)
= 5.148 × 10^(-9) mol S
<em>Step 2</em>. Use the molar mass of S to convert <em>moles of S to grams of S
</em>
Mass of S = 5.148 × 10^(-9) mol S × (32.06 g S/1 mol S) = 1.65 × 10^(-7) g S
I believe is 8.9 if rounded to the nearest hundredth but if not I’ll give it the whole answer and round to whatever is asking you the whole answer is 8.9399375975
