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

A

152

B

56

C

168

D

68

Text Solution

Verified by Experts

The correct Answer is:
C
As we know that
atomic mass=Equivalent weight`xx`valanecy
Mass of metal
`m=20xx3=60`
Hence its oxide=`M_(2)O_(3)`
`=(2xx60)+(3xx16)=168`.
