Answer to Question #280081 in General Chemistry for Mithun

Question

) In the reaction of AgNO3 (aq) and CaCl2 (aq) to produce Ca(NO3)2 (aq) and AgCl (s), a 

        chemist weighs out 5.35 g of AgNO3.  How many formula units of AgNO3 is the chemist 

        reacting?

Answer 1

2AgNO₃(aq) + CaCl₂(aq) → Ca(NO₃)₂(aq) + 2AgCl(s)

Molar mass of AgNO3 is 170 g/mol

Moles of AgNO3 $=\frac{5.35}{170}=0.03moles$
