The equivalent weight of a certain trivalent element is 20. Molecular weight of its oxide is

A

`168`

B

`68`

C

`152`

D

`56`

Text Solution

Verified by Experts

The correct Answer is:
A
At mass of element `= 20xx3=60`
Formula of its oxide is `M_(2)O_(3)`
`:.` Molecular mass of its oxide
`= 2xx60+16xx3`
`= 120 + 48 = 168`
