If the osmotic pressure of 5g per litre solution of compound at 27^(@)C is 0.025 atm, calculate the molecular mass of the compound.

A 0.109 g sample of a pure gaseous compound occupies 112 mL at 100^(@) C and 750 torr. What is the molecular mass of the compound ? Strategy : We first use the ideal gas law , pV = nRT , to find the number of moles of the gas . Then knowing the mass of that number of moles of the gas , we calculate the molar mass which is numerically equal to the molecular mass . Alternatively , we use Eq.(5.21) directly to get the molar mass.
