Concept introduction:
Freezing point can be calculated by using following formula,
(b)
Explanation of Solution
Freezing point is calculated as follows,
The freezing point is =
(c)
Interpretation:
For calculating molar mass of the large molecule, the best method with reason has to be given.
(c)
Explanation of Solution
In the colligative property, osmatic pressure method is the correct method for the calculating molar mass of the large molecule.
Because, the freezing point change is very small. Therefore, it is not possible to measure accurate value of molar mass of the large molecule.

If the volume of the fermentation medium is 500 ml, what is the concentration of ethanol in g/ml?arrow_forward
- You are given a clear solution. You are told that the solution is a 50.0 wt% solution and the molar concentration of the solute is 8.42 mol/L. You measure the density and find that it is 1.07 g/ml. What is the molar mass of the solute?arrow_forwardIf you compare the solubilities of the noble gases in water,you find that solubility increases from smallest atomicweight to largest, Ar < Kr < Xe. Which of the followingstatements is the best explanation? (a) The heavier the gas, the more it sinks to the bottom ofthe water and leaves room for more gas molecules at thetop of the water.(b) The heavier the gas, the more dispersion forces it has,and therefore the more attractive interactions it haswith water molecules.(c) The heavier the gas, the more likely it is to hydrogenbondwith water.(d) The heavier the gas, the more likely it is to make a saturatedsolution in water.arrow_forwardDetermine the amount of sodium chloride required to prepare 500 ml of a 3M sodium chloride solution.
