A solution made of toluene and benzene is prepared with a mole fraction of 0.7 for toluene. If the vapor pressure of pure toluene is 70 torr, and the vapor pressure of pure benzene is 190 torr, what is the total ideal vapor pressure contributed by toluene in this solution?
Would like to learn how to solve these thanks.

Table sugar granules were dissolved in a glass of water. The solid sugar granules have
no measurable vapor pressure, making water as the contributor to the entire vapor pressure
of the resulting solution. If sugar was added to the glass of water until the water makes up a
mole fraction of 0.75 in the solution, what is the total vapor pressure of the solution? Given
the following: vapor pressure of water at 25°C is 23.8 torr.
A. 23.8 torr
B. 5.95 torr
C. 29.75 torr
D. 17.9 tor
