Question

What is the theoretical yield of moles of hydrogen that can be produced from 0.032g of MG?

Answer 1

1.31x10⁻³ moles of H₂

Step-by-step explanation:

This is the equation:

Mg(s) + 2H₂O (g) → Mg(OH)₂ (aq) + H₂(g)

Ratio is 1:1, so 1 mol of Mg is needed to produce 1 mol of H₂

Mass / Molar mass = Mol

0.032 g / 24.3 g/m = 1.31x10⁻³ moles

1.31x10⁻³ moles of H₂(g)
