Answer:
[tex]\boxed{\math{6.02 \times 10^{23}} \text{ atoms of S }}[/tex]
Explanation:
1. Calculate the formula units of FeSO₄
There are 6.023 × 10²³ formula units in 1 mol of FeSO₄
[tex]\text{No. of formula units} = \text{1.00 mol FeSO}_{4} \times \dfrac{6.022\times 10^{23} \text{ units FeSO}_{4}}{\text{1 mol FeSO}_{4}}\\\\= 6.02\times 10^{23}\text{ formula units FeSO}_{4}[/tex]
2. Calculate the atoms of S
[tex]\text{No. of atoms} = 6.02 \times10^{23}\text {units FeSO}_{4} \times \dfrac{\text{1 atom S}}{\text{1 unit FeSO}_{4}}\\\\= \mathbf{6.02 \times 10^{23}} \textbf{ atoms S}\\\\\text{There are }\boxed{\mathbf{6.02 \times 10^{23}} \textbf{ atoms of S }} \text{ in 1.00 mol of FeSO}_{4}[/tex]
