Answer to Question #170668 in Chemistry for Vavine GI

Question

How many moles of water are produced when 5.00 moles of oxygen are used?

Answer 1

Solution:

The balanced chemical equation:

O₂ + 2H₂ → 2H₂O

According to the equation above: n(O₂) = n(H₂O)/2

Hence,

n(H₂O) = 2 × n(O₂) = 2 × 5.00 mol = 10.0 mol

n(H₂O) = 10.0 mol

Answer: 10.0 mol of water (H₂O) are produced.
