A mixture consisting of 0.150 M N2(g) and 0.612 M H2(g) reacts and then reaches equilibrium according to the equation:
N2(g) + 3H2(g) ⇋ 2NH3(g)
At equilibrium, the concentration of ammonia is 0.213 M. Calculate the concentration (molarity) of H2(g) at equilibrium to 3 decimal places. Do NOT enter any units.
