Calculate the mass of water (in grams) produced by the complete combustion of \( 16.0\text{ g} \) of methane (\( \text{CH}_4 \)), given the balanced reaction: \( \text{CH}_4(\text{g}) + 2\text{O}_2(\text{g}) \rightarrow \text{CO}_2(\text{g}) + 2\text{H}_2\text{O}(\text{g}) \).

Correct answer · Option D

36.0 g

1 mol of \( \text{CH}_4 \) (\( 16\text{ g} \)) produces 2 moles of \( \text{H}_2\text{O} \). Mass = \( 2 \times 18\text{ g} = 36\text{ g} \).
