Question
In the atomic weight determination, Dalton suggested the formula of water as HO and the composition of water as hydrogen = 12.5% and oxygen = 87.5% by weight. What should be the atomic weight of oxygen on H-scale, on the basis of this information?
Options
A.16
B.8
C.14
D.7
Solution
Atomic mass of oxygen = $\frac{87.5}{12.5} = 7$
