Be sure to answer every parts. The vapor push of ethanol (C2H,OH) in ~ 20°C is 44 mmHg, and also the vapor pressure of methanol (CH3OH) in ~ the very same temperature is 94 mmHg. A mixture that 32.3 g the methanol and 43.9 g of ethanol is prepared and also can it is in assumed to behave as perfect solution. Calculate the vapor pressure of methanol and also ethanol above this solution at 20°C. Be sure to report her answers come the correct number of far-ranging figures. Methanol mmHg Ethanol mmHg calculate the mol portion of methanoi and ethanol in the vapor above this equipment at 20°C. Methanol Ethanol
