In a mixture of 1 gm `H_(2)` and 8 gm `O_(2)`, the mole fraction of hydrogen is

A

`0.66`

B

`0.5`

C

`0.33`

D

`0.75`

Text Solution

Verified by Experts

The correct Answer is:
A
Number of moles of Hydrogen `=(1)/(2) = 0.5 = x `
Number of moles of Oxygen `= ( 8)/( 32) = 0.25 = y `
Mole fraction of Hydrogen `= ( x)/( x+ y ) `
