Answer:
There would be 4 moles of water (H20) produced.
Explanation:
Step 1: Data given
Number of moles of H2 = 4 moles
Molar mass of H2 = 2.02 g/mol
Suppose oxygen is in excess
Step 2: The balanced equation
2H2 + O2 → 2H2O
Step 3: Calculate moles of H2O
H2 is the limiting reactant.
For 2 moles of H2 consumed, we need 1 mol of O2 to produce 2 moles of H2O
For 4 moles of H2 we'll have 4 moles of H2O
There would be 4 moles of water (H20) produced.
