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) + 2H2(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?
