#4 How many moles of H2 is produced 

2. Write the balanced chemical equation between Mg(s) and HC1(ag).
Mg + 2HCI = MgCl, + H2
3. Find the number of moles of Mg(s) used in this experiment (Mg = 24.31 g/mol).
0.0450 g
= 0.00185 mol Mg
24.31g/mol
4. Find the number of moles of H2(g) (n(H2)) produced in this experiment (use the balanced
equation written in 2).
