  • Question 2
    4 / -1

    A solution having 4 g of polyvinyl chloride polymer in one litre of dioxane was found to have an osmotic pressure of 4.1×10-4 atmatm at 27℃. The approximate molecular weight of the polymer is:

  • Question 3
    4 / -1

    100 g of liquid A (molar mass: 140 g mol-1) was dissolved in 1000 g of liquid B (molar mass:180 g mol-1). The vapour pressure of pure liquid B was found to be 500 torr. What will be the vapour pressure of pure liquid A and its vapour pressure in the solution, respectively, if the total vapour pressure of the solution is 475 torr?
