A) 0.17 g
B) 0.21
C) 1 g
D) 0.7 g
E) 0.12 g
Correct Answer: E
Solution :
The relative atomic mass of oxygen =16 while its valency =2. So that the chemical equivalent \[E=\frac{16}{2}=8\] Chemical equivalent of hydrogen = 1 \[\frac{{{M}_{oxygen}}}{{{M}_{hydrogen}}}=\frac{{{E}_{oxygen}}}{{{E}_{hydrogen}}}=\frac{8}{1}\] \[\therefore \] \[{{M}_{hydrogen}}=\frac{{{M}_{oxygen}}}{8}=0.125\,g\]
