The vapor pressure of ethanol (C2H5OH) at 20°C is 44 mmHg, and the vapor pressure of methanol (CH3OH) at the same temperature is 94 mmHg. A mixture of 27.3 g of methanol and 43.1 g of ethanol is prepared and can be assumed to behave as an ideal solution. Calculate the vapor pressure of methanol and ethanol above this solution at 20°C. Be sure to report your answers to the correct number of significant figures. Methanol mmHg Ethanol mmHg Calculate the mol fraction of methanol and ethanol in the vapor above this solution at 20°C. Methanol Ethanol
