Can someone help me with this chemistry question?

Consider the reaction.

PCl5(g)鈫解垝鈭掆噣PCl3(g)+Cl2(g)饾惥c=0.0420

The concentrations of the products at equilibrium are [PCl3]=0.110 M and [Cl2]=0.230 M . What is the concentration of the reactant, PCl5 , at equilibrium?

    饾惥c = [PCl3] [Cl2] / [PCl5]

    0.0420 = (0.110) (0.230) / [PCl5]

    Solve for [PCl5] algebraically:

    PCl5 = 0.602 M
