How much calcium can be recovered from 75.0g of calcium fluoride

7nadin3 [17]

38.46g

Explanation:

Given parameters:

Mass of CaF₂ = 75.0g

Unknown:

Mass of calcium that can be recovered = ?

Solution:

This is a mass percentage problem and we need to solve it accordingly.

To solve this problem;

Find the molar mass of CaF₂

Find the ratio between the molar mass of Ca and that of CaF₂

Multiply by the given mass

Molar mass of CaF₂ = 40 + (2 x 19) = 78g/mol

Mass of calcium = $\frac{40}{78}$ x 75 = 38.46g
