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?
