1.) A vapor volume of 1.17 L forms when a sample of liquid CH3CN absorbs 1.00 KJ of heat at its normal boiling point (81.1 C and 1 atm). What is the heat of vaporization in KJ per moles of CH3CN?

2.) The vapor pressure of water at 25 C is 23.76 torr. If a 1.25 g sample of H20 is sealed into an evacuated 1.5 L container, will any liquid be present? If so, what mass of liquid.

For these questions, please describe the steps necessary to complete them. Answers are not necessary.
