![Kc=\frac{[NH_3]^2_{eq}}{[H_2]^3_{eq}[N_2]_{eq}}](/tpl/images/0143/1009/c1580.png)
is the unique unknown, solving for it one obtains:![[N_2]_{eq}=\frac{[NH_3]^2_{eq}}{[H_2]^3_{eq}Kc}](/tpl/images/0143/1009/e7601.png)
![[N_2]_{eq}=\frac{(0.050M)^2}{(0.250M)^3(6.0x10^{-2})}](/tpl/images/0143/1009/c87cf.png)
![[N_2]_{eq}=2.7M](/tpl/images/0143/1009/d60cf.png)
