Pressure of a mixture of 4 g of O_(2) and 2 g of H_(2) confined in a bulb of 1 litre at 0^(@)C is

Answer»

25.15 atm
31.025 atm
45.215 atm
15.210 atm

Solution :`n_(O_(2))=4//32=1//8" MOL",n_(H_(2))=2//2" mol"=1" mol"`
Total N=`9//8" mol"`
PV=nRT`"or"P=nRT//V`
`=(9//8)xx(0.0821)(273)//1=25.215" atm"`
