Step 1
To calculate the molality of sucrose, we need to know the mass of sucrose and the mass of the solvent (water) in kilograms. Molality is defined as the number of moles of solute (sucrose) divided by the mass of the solvent (water) in kilograms. Show more…

1. An aqueous solution of a nonionic (that is, nonelectrolyte) solute has a freezing point of -0.523 °C. The solution contains 2.68 g of solute dissolved in 61.1 g of H2O. What is the molar mass of the solute? g/mol 2. In a laboratory experiment, a student found that a 192-mL aqueous solution containing 2.744 g of a compound had an osmotic pressure of 14.8 mmHg at 298 K. The compound was also found to be nonvolatile and a nonelectrolyte. What is the molar mass of this compound? g/mol

Pure cyclohexane, C_6 H_12, has a freezing point of 6.53 ?. Its freezing point depression constant is: K_f=20.0 ?/m. A solution was made by taking 11.40g of an unknown nonelectrolyte and dissolving it in 150.0g of cyclohexane. The measured freezing point of the solution was 0.78?. Calculate the molar mass of the unknown nonelectrolyte.
