An element A (atomic weight = 12) and B ...

An element `A` (atomic weight = 12) and `B` (atomic weight = 35.5) combines ot form a compound `X`. If 4 mol of `B` comibnes with 1 mol of `A` to give 1 mol of `X`. The weight of 1 mol of `X` would be

A

`47.5 g`

B

`74.0 g`

C

`154.0 g`

D

`148.0 g`

Text Solution

Verified by Experts

The correct Answer is:
C
`4B + A rarr X`
`4 xx 35 + 12`
Weight of `X = 4 xx 35.5 + 12 = 154`
