ans. 20.9 torr,
Explanation-
Apply the formula-
(P0 – Ps)/P0 = X, where P0 = vapour pressure of pure water, Ps = V.P. of solution, X = mole fraction of solute in solution.
Molar mass of glucose = 180 g, and molar mass of water = 18 g.
Now you have sufficient information to solve this problem.
Thanks.
