Question

If 73.8 mL of an AgNO3 solution reacts with enough Cu to produce 0.241 g Ag by single displacement, what is the molarity of the initial AgNO3 solution if Cu(NO3)2 is the other product?

Answer 1

First you need a balanced equation

A2gNO3 + Cu == 2Ag + Cu(NO3)2

Now do the stoiciometry. Convert 0.241 Ag to moles and use the corect molar ratio to calculate moles of AgNO3.

Once you have the moles, divide by .0738 L to get the molarity.
