56 g of nitrogen and 96 g of oxygen are mixed isothermaly and at a total pressure of 10 atm. The partial pressures of oxygen and nitrogen (in atm) are respectively :

A

4,6

B

5,5

C

2,8

D

6,4

Text Solution

Verified by Experts

The correct Answer is:
A
mole of `N_(2)=56/28=2,` mole of `O_(2)=96/32=3`
`P_(O_(2))=2/5xx10=4` atm
`P_(N_(2))=3/5xx10=6` atm
