Calculate the total pressure in a mixtur...

Calculate the total pressure in a mixture of `4 g` of oxygen and `2 g` of hydrogen confined in a total volume of `1 L` at `0^(@)C`.

Text Solution

Verified by Experts

Total moles `(n)=(4)/(32)+(2)/(2)=(1)/(8)+1=(9)/(8)`
`P=nRT=(9)/(8)xx0.082xx273=25.18=25.2 atm`
