Question

Question 8. Give the ratio in
which hydrogen and oxygen are
present in water by volume.
(a) 1:2
(b) 1:1
(c) 2:1
(d) 1:8​

Answer 1

Answer:

(a) 1:2

Explanation:

the ratio of the masses of H with O is

H:O=1:8 = M1/M2

the ratio of their densities is

H:O=2:8=1:4 = D1/D2

hence ratio of their volumes is as follows.

Volume, V=M/D

so V1/V2=M1/M2×D2/D1 = (1/8)×4 = 1:2

Answer 2

The correct and exact answer is opt (a) : 1:2
