Answer 2

calcium is 0.2 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 calcium = 8 g

Molar mass of calcium = 40 g/mol

Putting values in above equation, we get:

$\text{Moles of calcium}=\frac{8g}{40g/mol}=0.2mol$
