Please help me With an in-depth explanation 

2.
Account for these facts:
(a) Although ethanol, C2H5OH (boiling point 80 °C), has a higher molar mass than water
(boiling point 100 °C), the alcohol has a lower boiling point.
(b) Mixing 50 mL of ethanol with 50 mL of water produces a solution with a volume
slightly less than 100 mL.
