A certain compound has the molecular formula `X_(4) O_(6)`. If 10g of `X_(4)O_(6)` has `5.72` g `X`, the 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
`("Molecular weight of" X _(4) O _(6))/( "Atomic weight of 4X") = ("Weigh of" X _(4) O _(6))/("Weight of X") `
`(4x + 96)/(4x) = (10)/( 5. 72) x = 32`
