SUMMARY
The discussion focuses on calculating the molarity, mole fraction, and molality of a glycerol-water solution with equal masses of glycerol (C3H8O3) and water, having a density of 1.10 g/mL. To find the molarity, the formula M = moles of solute/liters of solution is applied, alongside the mole fraction formula, mole fraction = n1/n(total), and the molality formula, molality = moles of solute/kg of solvent. The calculations begin with determining the moles of glycerol and water based on their equal masses and the total volume of the solution.
