A quantity of liquid methanol, CH;OH, is introduced into a rigid 3.00-L vessel, the vessel is sealed, and the temperature is raised to 500K. At this temperature, the methanol vaporizes and decomposes according to the reaction CH;OH(g) = CO(g)+2 H2(g), K= 6.90×10-1. If the concentration of H2 in the equilibrium mixture is 0.426M, what mass of introduced methanol was initially into the vessel? 247 g O 33.9 g O 74.3 g 29.0 g 25.8 g
