  • question_answer
    Pressure of a mixture of 4 g of \[{{O}_{2}}\] and 2 g of \[{{H}_{2}}\] confined in a bulb of 1 litre at \[{{0}^{o}}C\] is             [AIIMS 2000]

    A)                 25.215 atm         

    B)                 31.205 atm

    C)                 45.215 atm         

    D)                 15.210 atm

    Correct Answer: A

    Solution :

               no. of moles of \[{{O}_{2}}=\frac{4}{32}=0.125\]                    no. of moles of \[{{H}_{2}}=\frac{2}{2}=1\]                    total no. of moles = \[1+0.125=1.125\]                                 \[P=\frac{nRT}{V}=\frac{1.125\times 0.082\times 273}{1}=25.184atm.\]
