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

(a)`14`

B

(b)`28`

C

(c )`42`

D

(d)`56`

Text Solution

Verified by Experts

The correct Answer is:
A
Let the formula of oxide `=M_(2)O_(x)=44`
`2xxM+x xx 16 =44`
`2(Exx x)+x xx16=44`
`2(14xx x)+16 x=44`
`:. X=1`
atomic weight `=14xx1=14`
