A 200.5 g sample of methane (CH4) gas has a volume of 25.0 L at 25.0°C. Calculate the pressure using the ideal gas law. Calculate the corrected pressure using the Van der Waal's equation. (a - 2.25 atm*L2 *mol 2.b -0.0428 L'mol-1)
Under certain circumstances, carbon dioxide, CO2(g), can be made to react with hydrogen gas, H2(g), to produce methane, CH4(g), and water vapor, H2O(g): CO2(g)+4H2(g)→CH4(g)+2H2O(g) How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 53.6 moles of water vapor? Express your answer with the appropriate units. For example, write the unit moles as mol.
