Question

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

Answer 1

Correct Answer - d
(d) `"mole "N_(2)=(56)/(28)=2, " mole "O_(2)=(96)/(32)=3`
`P_(O_(2))=(2)/(5)xx10=4"atm"`
`P_(N_(2))=(3)/(5)xx10=6"atm"`
