A

45

B

9

C

18

D

27

Text Solution

Verified by Experts

The correct Answer is:
D
100 gm of metal oxide contains 53 g of metal ,
`:.` Equivalent mass of element
`=("Mass of element")/("Mass of oxygen")xx8=53/47xx8 ~~9`
`:.` Atomic mass = Equivalent mass of an element `xx` valency `=9xx3=27` gm.
