So, I'm doing a lab involving galvanic cells and I need to figure out a nonstandard cell potential.  The problem is, I'm not too sure how to figure out the reaction quotient (Q). It's probably something really simple that I missed or something, but still, could someone please help me out?

My substances are Cu(s) as my cathode and Mg(s) as my anode. The Cu(aq) was diluted down to 0.6 mol/L and the Mg(aq) was kept at 1.0 mol/L.

My balanced equation is as follows (charges in the brackets):
2e(-) + Cu(2+) + Mg -> Cu + Mg(2+) + 2e(-)

If you could help me out, that would be great.
Thanks a lot!
