Magnesium fluoride is used in the ceramics and glass industry. What is the mass of 1.72 mol of magnesium fluoride?

107g

Explanation:

Magnesium fluoride (MgF₂) has a molecular mass of:

Mg: 24,305 g/mol × 1 = 24,305 g/mol

F: 18,998 g/mol × 2 = 37,996 g/mol

MgF₂ = 24,305g/mol + 37,996g/mol = 62,301g/mol. That means the mass of 1,72 mol of MgF₂ is:

1,72 mol F₂ × (62,301g / 1mol) = 107g
