40.0 g of a solute is dissolved in 500. mL of a solvent to give a solution with a volume of 515 mL. The solvent has a density of 1.00 g/mL. Which statement about this solution is correct? (A) The molarity is greater than the molality. (B) The molarity is lower than the molality. (C) The molarity is the same as the molality. (D) The molarity and molality cannot be compared without knowing the solute.
Answer is B. Why is that?
