Calculate the freezing point and the boiling point of each of the following aqueous solutions. (Assume complete dissociation. Assume that water freezes at 0.00°C and boils at 100.000°C.)
Kf = 1.86 °C/molal
Kb = 0.51 °C/molal
0.050 m MgCl2
Tf = °C
Tb = °C
0.050 m FeCl2
Tf = °C
Tb = °C
An aqueous solution of 11.00 g of catalase, an enzyme found in the liver, has a volume of 1.00 L at 27°C. The solution's osmotic pressure at 27°C is found to be 0.820 torr. Calculate the molar mass of catalase.
Molar mass = g/mol
