In the atomic weight determination, Dalton suggested the formula of water as HO and the composition of water as hydrogen = 12% and oxygen = 87.5%, by weight. What should be the atomic weight of oxygen on H-scale, on the basis of this information?

A

16

B

8

C

14

D

7

Text Solution

Verified by Experts

The correct Answer is:
D
`(n_(H) xx w_(H))/(n_(0) xx w_(0)) = (12.5)/(87.5) rArr (1 xx w_(H))/(1 xx W_(O)) = (1)/(7) rArr 7 W_(H) = W_(O)`, Atomic weight of oxygen of this H-scale will be 7
