    What should be the weight and moles of \[AgCl\]precipitate obtained on adding 500ml of 0.20 M \[HCl\]in 30 g of \[AgN{{O}_{3}}\]solution? (\[AgN{{O}_{3}}\]= 170)

    A)                 14.35 g  

    B)                 15 g

    C)                 18 g       

    D)                 19 g

    Correct Answer: A

    Solution :

                        \[AgN{{O}_{3}}+HCl\to AgCl+HN{{O}_{3}}\]                             \[\frac{30}{170}\]      \[\frac{500\times 0.2}{1000}\]                    t =0  0.176 mole  0.1 mole limiting    =14.345gm                 t =t   0.076 mole  0                               0.1mole
