A metal M of equivalent mass E forms an ...

A metal `M` of equivalent mass `E` forms an oxide of molecular formula `M_(x)O_(y)` The atomic mass of the metal is given by the correct equation .

A

`(2En)/(m)`

B

2mEn

C

`(E )/(n)`

D

`(ME)/(2n)`

Text Solution

Verified by Experts

The correct Answer is:
A
Amount of X that combines with 8 g of oxygen,
i.e., `E=(m xx"Atomic mass")/(n xx2)`
`therefore " Atomic mass"=(2En)/(m)`
