Question

Calculate the
the ratio
ratio by number of
of atoms
in water molecule? (Mass Ratio of hio in
Water is (1:8)
​

Answer 1

Explanation:

Given that the ratio of molecular weight of Hydrogen and Oxygen in water is 1:8

Let the amount of hydrogen be x and the amount of oxygen be y

Given that x:y=1:8

⟹

y

x

=

8

1

⟹y=8x -------(1)

Given that oxygen is 12gm

Therefore, the amount of hydrogen is 12=8x

⟹x=

8

12

⟹x=

2

3

Given the quantity of hydrogen =32gm

So, the quantity of oxygen is y=8×32

⟹y=256gms
