A certain compound has the molecular formula `M_4O_6` . If 10.0 g of the compound contains 5.62 g of M, then the atomic mass of M is

A

62.0 u

B

6.8 u

C

30.8 u

D

42 u

Text Solution

Verified by Experts

The correct Answer is:
C
If x is the atomic mass of A , then
`(4x)/(4x + 96) xx 10g = 5.62 therefore x = 30.8 `amu
