A quantity of liquid methanol, CH3OH, is introduced into a rigid 2.45-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 = 0.83 If the concentration of H2 in the equilibrium mixture is 0.648 M, what mass of methanol was initially introduced into the vessel? (MW (CH3OH) = 32 g/mol).
