Question

9.)Moles of solute (mol)

Use the molality to convert kg of solvent to moles of solute.

10.)Molar mass of the solute (g/mol)

Use the mass of solute you weighed out in the simulation and moles of solute calculated in the previous step.

11.)Percent error for the molar mass of the solute

% error=∣∣∣true value−experiment valuetrue value∣∣∣×100% error=|true value-experiment valuetrue value|×100

The true value for the molar mass of NaCl is 58.44 g/mol.

Information found so far: Mass NaCl (g) 5.8871

Vol of water mL 100.0

Mass ice (g) 51.5023

Freezing point of solution (C) -2.85

Predicted value of i for NaCl is 2

Molarity of solution (m) 0.76612903225806

Mass of solvent in grams 151.5g

Mass of solvent in kg 0.1515kg
