Default Density Hw

An enmpty pycnometer weighed 25.296g. When filled with water at 25C, it weighed 34.914g. When filled with unknown liquid, it weighed 33.485g. Give the density of water is 0.99705g/mL. Calculate the density of the unknown liquid.

Chloroform has a density of 1.492g/mL and propylene glycol has a density of 1.043g/mL. When 35.00mL of chloroform and 25.70mL of propylene glycol mixed together, what is the density of the mixture?
