Question
How many liters of H2 gas are produced when 67.5 g of solid magnesium react with excess aqueous HCl at 2.00 atm and 310. K?
Mg(s) + 2HCl (aq) ⟶ H2 (g) + MgCl2(aq)
Expert Solution

Step 1
Given that :
Mass of Mg = 67.5 g
Molar mass of Mg = 24.3 g/mol
Moles of Mg = 67.5g÷24.3g/mol = 2.78 mol
Step by step
Solved in 2 steps
