Answer:

27.74%

Step-by-step explanation:

The molar mass of Mg can be found on the periodic table: 24.31 g/mol.

To calculate the molar mass of Mg₃(PO₄)₂, we need to consider the individual elements' molar masses:

The molar mass of P is 30.97 g/mol.

The molar mass of O is 16.00 g/mol.

Molar mass of Mg₃(PO₄)₂ = 262 g/mol

Mass of Mg in Mg₃(PO₄)₂ = 24×3 = 72 g

percentage composition of Mg in Mg₃(PO₄)₂

(72*100) / 262 = 27.74%
