Yes. Just like in part a, there is a certain ratio between the masses of hydrogen and oxygen in all three samples. In this case, the hydrogen-oxygen ratio is $1$:$16$.
Just like in part a, you should divide the given masses of hydrogen by the respective masses of oxygen. In all three samples, you will get a ratio of $\frac{1}{16}$.
