Question from discussion section

Hi everyone,

I have a question from a worksheet in discussion

1.) For a reaction given below, 2.00 moles of A and 3.00 moles of B are placed in a 6.00 L container. At equilibrium, the concentration of A is 0.303 mol/L. What is the concentration of B at equilibrium?

I'm not sure how to organize and use all the components given in the problem, could someone go over it please?

First find the initial concentrations of A and B by dividing moles of A and B by the overall volume (6L).
Then plug this information along with the equilibrium concentration of A into the ICE table.
Assuming they give you the equilibrium constant, you should then be able to find x, which will in turn allow you to find the equilibrium concentration of B.

Oh okay thanks! that makes sense
