Answer 2

The number of moles of iron added is 0.0347 moles

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Given mass of iron = 1.94 g

Molar mass of iron = 55.84 g/mol

Putting values in above equation, we get:

$\text{Moles of iron}=\frac{1.94g}{55.84g/mol}=0.0347mol$
