Answer

Explanation:

Step1: Set up proportion

Let $x$ be the amount of hydrogen in 79.2 g of water. We know the ratio of hydrogen to water is constant. So $\frac{0.111}{1}=\frac{x}{79.2}$.

Step2: Solve for $x$

Cross - multiply: $x = 0.111\times79.2$. $x=0.111\times79.2 = 8.7912\approx8$ g.

Answer:

C. 8 g
