What volume of 0.55M nickel (II) nitrate, Ni(NO3)2, will react with 85mL of 0.25M potassium carbonate, K2CO3, to form nickel (II) carbonate, NiCO3, and potassium nitrate, KNO3?


How would I go about solving the problem? I do know the answer is around 39mL but I don't know how the answer is found.  I got as far as balancing the equation, and finding the moles of potassium carbonate - 0.02125 mol, after that I'm stuck.


I'll be thankful for all the help I can get.

start with a balanced equation

search for the amount of moles for potassium carbonate first. Since the amount of moles of potassium carbonate and nickel nitrate is the same in the balanced equation, and with the molarity of nickel nitrate given, the volume of the solution can be found. final answer should be 38.63ml.
