CH3OH can be synthesized by the following reaction.?
CH3OH can be synthesized through the following reaction:
CO(g) + 2H2(g) → CH3OH(g)
Part A: What volume of H2 gas (in liters), measured at 744 mmHg and 84°C, is required to synthesize 25.4 g of CH3OH?
Part B: How many liters of CO gas, measured under the same conditions, are required?

Part A
CO + 2 H2 → CH3OH
(25.4 g CH3OH) / (32.0420 g CH3OH/mol) x (2 mol H2 / 1 mol CH3OH) =
1.5854 mol H2
V = nRT / P = (1.5854 mol) x (62.36367 L mmHg/K mol) x (84 + 273 K) /
(744 mmHg) = 47.4 L H2
Part B
(25.4 g CH3OH) / (32.0420 g CH3OH/mol) x (1 mol CO2 / 1 mol CH3OH) =
0.79271 mol CO2
(0.79271 mol) x (62.36367 L mmHg/K mol) x (84 + 273 K) /
(744 mmHg) = 23.7 L CO2
