Answer:
The answer to your question is: a. Hydrogen-1
Explanation:
Hydrogen-1 (1.07 u)
Hydrogen-2 (2.02 u)
Hydrogen-3 (3.01 u)
Periodic table says that H has an atomic mas of 1.008
Then, the reported atomic mass is closer to the mass of the smaller isotope, so Hydrogen-1 must be present in larger percentage.
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
