Question

How many atoms of sulfur are in 1.00 mol of iron(II) sulfate, FeSO4 ?

Answer 1

6.02 x 10^23 atoms of FeSO4

Answer 2

`\boxed{\math{6.02 * 10^(23)} \text{ atoms of S }}`

Step-by-step explanation:

1. Calculate the formula units of FeSO₄

There are 6.023 × 10²³ formula units in 1 mol of FeSO₄

`\text{No. of formula units} = \text{1.00 mol FeSO}_(4) * \frac{6.022* 10^(23) \text{ units FeSO}_(4)}{\text{1 mol FeSO}_(4)}\\\\= 6.02* 10^(23)\text{ formula units FeSO}_(4)`

2. Calculate the atoms of S

`\text{No. of atoms} = 6.02 *10^(23)\text {units FeSO}_(4) * \frac{\text{1 atom S}}{\text{1 unit FeSO}_(4)}\\\\= \mathbf{6.02 * 10^(23)} \textbf{ atoms S}\\\\\text{There are }\boxed{\mathbf{6.02 * 10^(23)} \textbf{ atoms of S }} \text{ in 1.00 mol of FeSO}_(4)`
