At a certain temperature K c = 36 for H 2(g) + I 2(g) rightleftharpoons 2 HI (g). If 1.0 mol of H 2 and 1.0 mol of I 2 are placed in a sealed 1.0 L flask, what is [ HI ] at equilibrium?

At a certain temperature $K_{c} = 36$ for $H_{2} (g) + I_{2} (g) ⇌ 2 HI (g)$ . If $1.0 mol$ of $H_{2}$ and $1.0 mol$ of $I_{2}$ are placed in a sealed $1.0 L$ flask, what is $[HI]$ at equilibrium?
