Explain what mass of ethanol is present in the vapor

Reference no: EM13181944

A small amount of liquid ethanol (.26g, C2H5OH) is placed in a 4.7-L bottle and tightly sealed. The bottle is placed in a refrigerator/freezer where the liquid reaches equilibrum, with its vapor at -11 degrees C.

A) What mass of ethanol is present in the vapor? (the vapor pressure of ethanol is 10.0 torr at -2.3 degrees C and 40.0 torr at 19 degrees C.)

B)When the container is removed and warmed to room temperature, 20 degrees C will all teh ethanol vaporze?

a)No, all the ethanol will not vaporize

b) Yes, all the ethanol will vaporize
