In a compound such as water, the ratio of the mass of hydrogen to the mass of oxygen is always ______ in ratio.1 pointa) 1 : 8b) 3 : 16c) 1 : 2d) none of these

To determine the ratio of the mass of hydrogen to the mass of oxygen in a compound like water, we need to consider the atomic masses of hydrogen and oxygen.

The atomic mass of hydrogen is approximately 1 gram per mole, while the atomic mass of oxygen is approximately 16 grams per mole.

In water (H2O), there are two hydrogen atoms and one oxygen atom.

Therefore, the total mass of hydrogen in water is 2 grams (2 moles of hydrogen x 1 gram per mole), and the total mass of oxygen is 16 grams (1 mole of oxygen x 16 grams per mole).

To find the ratio of the mass of hydrogen to the mass of oxygen, we divide the mass of hydrogen by the mass of oxygen.

So, the ratio is 2 grams of hydrogen to 16 grams of oxygen, which simplifies to 1:8.

Therefore, the correct answer is a) 1:8.
