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

Answer»

25.215 atm
31.205 atm
45.215 atm
15.210 atm

Solution :No. of moles of `O_(2)=(4)/(32)=0.125`
No. of moles of `H_(2)=(2)/(2) =1`
Total no. of moles` = 1+0.125= 1.125`
`P= (nRT)/(V)= (1.125 XX 0.0821 xx 273)/(1)=25.21 atm`
