Problem 1PE
Calculation of Molality
A solution is made by dissolving 4.35 g of glucose (C6H12O6) in 25.0 mL of water at 25 °C.
Calculate the molality of glucose in the solution. Water has a density of 1.00 g/mL.
Suppose you take a solution and add more solvent, so that the original mass of solvent is doubled. You take this new solution and add more solute, so that the original mass of the solute is doubled. What happens to the molality of the final solution, compared to the original molality?
(a) It is doubled.
(b) It is decreased by half.
(c) It is unchanged.
(d) It will increase or decrease depending on the molar mass of the solute.
(e) There is no way to tell without knowing the molar mass of the solute
