The percentage of element M is 53 in its oxide of molecular formula `M_(2)O_(3)`. Its atomic mass is about

A

45

B

9

C

18

D

36

Text Solution

Verified by Experts

The correct Answer is:
D
100 g of metal oxide contains 53 g of metal,
`therefore ` Equivalent mass of elements.
` = ("Mass of element")/("Mass of oxygen") xx = (53)/(47) xx 8 ~~9`
`therefore ` Atomic mass = Equivalent mass of an element × valency
` = 9 xx 3 =27 g`
