A quantity of liquid methanol, CH3OH, is introduced into a rigid 3.00-L vessel, the vessel is sealed, and the temperature is raised to 500 K. At this temperature, the methanol vaporizes and decomposes according to the reaction CH3OH(g) 
CO(g) + 2 H2(g) , Kc = 6.90 × 10-2
If the concentration of H2 in the equilibrium mixture is 0.426 M, what mass of methanol was initially introduced into the vessel?
