@TalentedFBG โข1 mole of Mg produces 1 mole of Hโ.
So,
\text{Moles of H}_2 = 0.1333\ \text{mol}
Step 3: Calculate the mass of hydrogen
Molar mass of Hโ = 2 g/mol
\text{Mass of H}_2 = 0.1333 \times 2 = 0.2667\ \text{g}
Answer:
Mass of hydrogen produced = 0.27 g (to 2 decimal places).
@TalentedFBG The balanced chemical equation is:
\mathrm{Mg + H_2SO_4 \rightarrow MgSO_4 + H_2}
Step 1: Calculate the moles of magnesium
Atomic mass of Mg = 24 g/mol
\text{Moles of Mg} = \frac{3.2}{24} = 0.1333\ \text{mol}
