A compound has the molecular formula `X_(4)O_(6)`. If `10 g "of" X_(4)O_(6)` has `5.72 g X`, atomic mass of `X` is:

A

32 amu

B

37 amu

C

42 amu

D

98 amu

Text Solution

Verified by Experts

The correct Answer is:
A
Let the atomic weight of `X` of `x`
mol of `X_4O_6=` mol of `X`
`implies("weight of "X_4O_6)/("atomic weight of "X_4O_6)=("Wt. of X")/("At. Wt. of 4X")`
`implies(10)/(4x+6+16)=(5.72)/(4x)`
`x=32`
