Calculate the molecular mass of glucose.

Colligative properties can be used to determine the molecular mass of solutes in solutions. For determining the molecular mass of polymers, osmotic pressure is preffered to other properties. Why ?

The pressure of a vessel that contained pure oxygen dropped from 2000 torr to 1500 torr in 40 min as the oxygen leaked through a small hole into a vacuum. When the same vessel was filled with another gas, the pressure dropped from 2000 torr to 1500 torr in 80 min. The molecular mass of second gas is

If the vapour density of a gas with respect to methane is 2, molecular mass of the gas will be
