    To prepare a solution with concentration of 0.03 g/mL of \[AgN{{O}_{3}},\]what amount of \[AgN{{O}_{3}}\]should be added in 60 mL of solution?

    A)  1.8 g             

    B)       0.18 g

    C)       0.8 g             

    D)       0.09 g            

    Correct Answer: A

    Solution :

    Concentration in terms of g/mL is given as \[0.03=\frac{\text{Mass}\,\text{of}\,\text{AgN}{{\text{O}}_{\text{3}}}}{\text{60}}\] Mass of \[AgN{{O}_{3}}=60\times 0.03=1.8\,g.\] Hence, the correct option is (a).
