The freezing point of cyclohexane is 6.50°C. For cyclohexane solvent Kf=20.0. 0.140 g of an unknown solute is dissolved in 7.88 g of cyclohexane (C6H12). The freezing point of the solution was 3.30°C. Calculate the corresponding molar mass of the solute. (g/mol)
The freezing point of cyclohexane is 6.50°C.
For cyclohexane solvent Kf=20.0.
0.140 g of an unknown solute is dissolved in 7.88 g of cyclohexane (C6H12).
The freezing point of the solution was 3.30°C.
Calculate the corresponding molar mass of the solute. (g/mol)
To the above solution a further 0.132 g of the unknown is dissolved.
The freezing point of the resulting solution was 0.81°C.
Calculate the corresponding molar mass of the solute. (g/mol)
To the above solution a further 0.130 g of the unknown is dissolved.
The freezing point of the resulting solution was -2.66°C.
Calculate the corresponding molar mass of the solute. (g/mol)
Calculate the mean molar mass of the solute. (g/mol)
Calculate the half-range uncertainty. + - (g/mol)
