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 x be valency of element M `rArr` Formula of oxide is `M_(2)O_(x)`
Now, `(2 xx x xx 14) = 44 rArr x = 1 rArr` Atomic weight of element `= 14 xx 1 = 14`
