  • question_answer The molarity of a solution containing 5 g of \[NaOH\] in 250 ml solution

    A)  0.5                             

    B)  1.0                 

    C)       1.3                 

    D)       4.0                             

    Correct Answer: A

    Solution :

    As the molarity of solution \[=\frac{\text{Weight}\,\text{of}\,\text{solute}}{\text{Molecular weight}\,\text{of solute  }\!\!\times\!\!\text{  Volume of solution}}\] \[=\frac{5\times 1000}{40\times 250}\] \[=0.5\] Hence, the correct option is (a).
