Please give some explanation for every question. Thank you!

Q1: A solution is made by dissolving 4.35 g of glucose (C6H12O6) in 25.0 mL of water at 25 oC. Calculate the molality of glucose in the solution. Water has a density of 1.00 g ⁄ mL. What is the mole fraction of glucose?
Q2: An aqueous solution of hydrochloric acid contains 36% HCl by mass.
(a)Calculate the mole fraction of HCl in the solution
(b) Calculate the molality of HCl in the solution
Q3: A solution with a density of 0.876 g/mL contains 5.0 g of toluene (C7H8) and 225 g of benzene. Calculate the molarity of the solution.
Q5: Glycerin (C3H8O3) is a nonvolatile nonelectrolyte with a density of 1.26 g/mL at 25 oC. Calculate the vapor pressure at 25 oC of a solution made by adding 50.0 mL of glycerin to 500.0 mL of water. The vapor pressure of pure water at 25 oC is 23.8 torr, and its density is 1.00 g/mL.
