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 _(2) B _(2)`

`AB _(3)`

`A_(3) B`

Text Solution

Verified by Experts

The correct Answer is:

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