  • question_answer
    In an experiment during the analysis of a carbon compound, 145 \[l\] of \[{{H}_{2}}\] was collected at 760 mm Hg pressure and \[{{27}^{o}}C\] temperature. The mass of \[{{H}_{2}}\] is nearly [MNR 1987]

    A)                 10 g       

    B)                 12 g

    C)                 24 g       

    D)                 6 g

    Correct Answer: B

    Solution :

                    \[PV=nRT\], \[n=\frac{PV}{RT}=\frac{1\times 145}{0.082\times 3}=5.8\approx 6\,mole\].
