1.) A solution of ethanol (CH3CH2OH, density 0.795 g/mL) is prepared by placing 30.0 mL of ethanol in a 200.00 mL volumetric flask and diluting with water to the etched mark.

a.) What is the molarity of the solution?

b.) Next, 25.00 mL of this solution is placed in a 500.00 mL volumetric flask and diluted to the mark.

c.) What is the molarity of the new solution?

2.) If the temperature of a sample of water requires 3.2 KJ of heat to raise the temperature from 26.1 C to 36.2 C, how much water was in the sample?
