A system is represented by the following equation:
2A(aq) + B(aq) --> 3C(aq)
At equilibrium, [C]=0.6 M. Calculate the value of K if initially 1 mol of A and 2 mol of B were placed in a 1 L flask.

we will assume that the aqueous solutions fill the 1 L flask.
1 mol A + 2 mol B and 0 mol C
1-2x mol of A and 2-x mol of B and 3x mol of C
so x=0.2 M
K=0.012 (with no units)

I am having trouble with this question so I decided to check online. The question sheet in which I got this question from came with an answer sheet, and it says the answer for k = 0.33. Another online source gave an answer of 0.024. I'm not sure what values are needed in the change row.
2A + B <----> 3C
INITIAL 1 2 0
EQUILIBRIUM 0.6 M
If 0.6 = 3x, x should equal 0.2? How is x affecting A + B?
