As per your syllabus, what mass of WATER is produced by the combustion of 16 g of methane (CH₄)?
A16 g
B32 g
C36 g (1 mol CH₄ → 2 mol H₂O; 2 × 18 = 36 g)
D18 g
Answer & Solution
Correct answer: C. 36 g (1 mol CH₄ → 2 mol H₂O; 2 × 18 = 36 g)
As per your syllabus, 16 g CH₄ = 1 mol; produces 2 mol H₂O = 2 × 18 = 36 g water.
