On reduction with hydrogen, 3.6 g of an ...

On reduction with hydrogen, `3.6 g` of an oxide of matel left `3.2 g` of metal. If the vapour density of metal is `32`, the simplest formula of the oxide would be

A

`MO`

B

`M_(2)O_(3)`

C

`M_(2)O`

D

`M_(2)O_(5)`

Text Solution

Verified by Experts

The correct Answer is:
C
As we know that
Equivalent weight `=("weight of metal")/("weight of oxygen")xx8`
`=3.2/0.4xx8=64`
Vapour density `=("mol. wt")/2`
Mol. Wt`=2xxV.D=2xx32=64`
As we know that `n=("mol. wt")/("eq. wt")=64/64=1`
Suppose, the formula of metal oxide be `M_(2)O_(n)`. Hence the formula of metal oxide `=M_(2)O`.
