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

    A) 1.8g                                       

    B) 0.8 g

    C) 0.18 g                                   

    D) none of these

    Correct Answer: A

    Solution :

    Concentration in terms of g/mL is given as \[0.03=\frac{mass\,of\,AgN{{O}_{3}}}{60}\] Mass of \[AgN{{O}_{3}}=60\times 0.03=1.8\text{ }g\]
