  • question_answer
    100 mL of 1 M \[HCl\] is mixed with 50 mL of 2 M \[HCl\]. Hence, \[\left[ {{H}_{3}}{{O}^{+}} \right]\] is:

    A) 1.00 M

    B) 1.50 M      

    C) 1.33 M

    D) 3.00 M

    Correct Answer: C

    Solution :

    [c] Resultant \[[{{H}^{+}}]=\] \[\frac{{{M}_{1}}{{V}_{1}}+{{M}_{2}}{{V}_{2}}}{{{V}_{1}}+{{V}_{2}}}=\frac{100+100}{150}=1.33M\]
