A compound made of two elements A and B ...

A compound made of two elements A and B is found to contain 25% A (atomic mass `12.5`) and 75% B (atomic mass `37.5`). The simplest formula of the compound is

A

`AB`

B

`A_(2)B_(2)`

C

`AB_3`

D

`A_(3)B`

Text Solution

Verified by Experts

The correct Answer is:
A

Mole ratio of A to B is `(25)/(12.5):(75)/(37.5)=2:2`. `MF=A_(2)B_(2)`. The simplest formula will be AB.
