81.875 g of magnesium phosphate Mg₂(PO₄)₃
Explanation:
The chemical formula of magnesium phosphate is Mg₃(PO₄)₂.
molar mass of Mg₃(PO₄)₂ = atomic weight of Mg × 3 + atomic weight of P × 3 + atomic weight of O × 3 × 4
molar mass of Mg₃(PO₄)₂ = 24 × 3 + 31 × 2 + 16 × 2 × 4 = 262 g/mole
Knowing the molar mass of Mg₃(PO₄)₂, we devise the following reasoning:
if in 262 g of Mg₂(PO₄)₃ there are 48 g of Mg
then in X g of Mg₂(PO₄)₃ there are 15 g of Mg
X = (262 × 15) / 48 = 81.875 g of Mg₂(PO₄)₃

Answer:
1386g
Explanation:
Solubility of a solute is the ability of the solute to mix into a liquid (the solvent). It measures the highest amount of substance mixed into a liquid solvent while they are both at equal amounts.
if 14g dissolved in 100cm3
the amount that will dissolve in 1000cm3 = 14 x 1000/ 100
=1400g
To form a saturated solution, 1400 - 14 = 1386g must be added.
