... Rearranging gives x = [I2(g)] = 0.0139 M. Answer: 0.0139 M If 0.274 g of H2S were now introduced into the same flask, what would be the concentration of S2(g) at equilibrium? The molar mass of H2S is (2 × 1.008 (H) + 32.06 (S)) = 34.08 g mol-1. Hence, 0.274 g of H2S corresponds to: number of moles = ...
