Consider the reaction. 2 cap h sub 2 plus cap o sub 2 rightarrow 2 cap h sub 2 cap o How many moles of water are produced from 13 point 3 5 mol of oxygen?

The balanced equation shows that 1 mol of oxygen (O₂) produces 2 mol of water (H₂O). Multiply 13.35 mol O₂ by the ratio 2 mol H₂O per 1 mol O₂: 13.35 × 2 = 26.70 mol H₂O. Therefore, 26.70 mol is produced, which is choice B.
