Question

in a compound such as water , the ratio of the mass of hydrogen to the ogygen is always (a) 1:8 (b) 2:18 (c) 1:16 (c) 3:16​

Answer 1

1:8

In a compound such as water, the ratio of the mass of hydrogen to the mass of oxygen is always 1:8, whatever the source of water. Thus, if 9 g of water is decomposed, 1 g of hydrogen and 8 g of oxygen are always obtained.
