Explanation:
Answer:

Explanation:
We will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.
Mᵣ: 24.30
Mg + 2H⁺ ⟶ Mg²⁺ + H₂
n/mol: 1.98 × 10⁻²³
1. Calculate the moles of Mg
The molar ratio is 1 mol Mg:1 mol H₂

2. Calculate the mass of Mg
