The Mw of a oxide of an element is 44. the Ew of the element is 14. the atomic weight of the element is

A

14

B

28

C

42

D

56

Text Solution

Verified by Experts

The correct Answer is:
A
Let the formula of oxide = `M_(2)O_(x)=44`
`2xxM+x xx16=44`
`2(Exxx)+x xx16=44`
`2(14xxx)+16x=44`
`thereforex=1`
Atomic weight = `14xx1=14`
