Answer to Question #152630 in General Chemistry for Minowa Vang

Question

Cu_(s) + AgNO_3(aq) ---> CuNO_3(aq) + Ag_(s)

How many grams of silver would be produced if you began with 10 grams of copper?

Answer 1

MM(Cu) = 63.5 g/mol

$n(Cu) = \frac{10}{63.5} = 0.157 \;mol$

n(Ag) = n(Cu) = 0.157 mol

MM(Ag) = 107.8 g/mol

$m(Ag) = 0.157 \times 107.8 = 16.92 \;g$

Answer: 16.92 g
