When the contents of a 1000 cubic foot container full of basketballs is mixed with the contents of a 200 cubic foot container full of ping pong balls, the mixture does not completely fill a 1200 cubic foot container. explain this result in terms of the partial molar volumes of the basketballs and ping pong balls. state any assumptions you make.

Consider a 0.487 L solution of the amino aspartic acid (0.685 M), which ahs a carboxylic acid group (pKa = 2.10), an amine group (pKa = 9.82), and a carboxylic acid side chain (pKa = 3.86). How many liters of 2.59 M NaOH would you need to add to reach the isoelectric point of the amino acid?

The osmotic pressure of an unknown substance dissolved in 100 mL of water is measured at 298 K. The concentration of this substance is 25.5 kg m–3 and the osmotic pressure is 4.50 x 104 Pa. a) Determine the molecular weight of this substance. b) Calculate the change in the freezing point of water caused by the addition of this substance. (Keep in mind that the density of a dilute aqueous solution is approximately 1 g/mL).

U-236 is an important neutron poison in reactors that is created in uraniumbased fuels from U-235 capturing a neutron. Derive an expression for the time at which the peak U-236 concentration occurs. Note that not all neutron absorption by U-235 becomes U-236; some U-235 atoms fission.
