The number of moles present in 34.5 g of HSO is

A

0.5

B

0.7

C

2.4

D

1.3

Text Solution

Verified by Experts

The correct Answer is:
A
`P_T=P_A+P_B=3P_B`
So, `P_B=2/3` and `P_A=2-2/3=4/3` Now `P_A/P_B=n_1/n_2=2`
So, `n_1=2n_2`
`P_T V=n_T R_T`
`2xx8.21=n_Txx0.082xx50`
`n_T=4=n_1+n_2 " " So, n_2=4/3 " " n_1=8/3`
