Calculating concentration of product & mass of a precipitate

[lockandkey213]

The question is:
100 mL of 0.2 mol/L sodium carbonate solution and 200 mL of 0.1 mol/L calcium nitrate solution are mixed together. Calculate the mass of calcium carbonate that would precipitate and the concentration of the sodium nitrate solution that will be produced.

I believe the balanced equation would be: 3Na2CO3 + Ca3(NO3)2 ---> 3CaCO3 + 2Na3NO3
I'm not quite sure where to go from there. Please help!

There are a number of steps involved. A good idea is to write down what you know, what you don't know and how to obtain certain values (e.g. at the end, you need mass, how do you get mass from moles might be useful). Firstly, I am guessing it goes to completion? You know the number of moles that participates in a general reaction (3Na2CO3 + Ca3(NO3)2 ---> 3CaCO3 + 2Na3NO3), what does that tell you?
