Question

What volume of H₂O(g) is produced when 2.00 mol of C₂H₄(g) reacts with oxygen gas at STP?

C2H4(g)+3O2(g)⟶2CO2(g)+2H2O(g)

Answer 1

Answer #1

We are given the following balanced chemical reaction as

C2H4(g)+3O2(g)⟶2CO2(g)+2H2O(g)

1 mole of C2H4 produces 2 moles of H2O

Thus, 2 moles of C2H4 will produce 4 moles of H2O

Now, Each mole of gas occupies 22.4 L at STP

Therefore, volume of H2O = 4 * 22.4 = 89.6 L
