  • question_answer
    A solution contains \[25%{{H}_{2}}O\],\[25%{{C}_{2}}{{H}_{5}}OH\] and \[50%\,C{{H}_{3}}\,COOH\] by mass. The mole fraction of \[{{H}_{2}}O\] would be

    A)                 0.25       

    B)                 2.5

    C)                 0.503     

    D)                 5.03

    Correct Answer: C

    Solution :

    \[{{X}_{{{H}_{2}}O}}=\frac{{{n}_{{{H}_{2}}O}}}{{{n}_{{{H}_{2}}O}}+{{n}_{{{C}_{2}}{{H}_{5}}OH}}+{{n}_{C{{H}_{3}}COOH}}}\]
