In the Freezing Point Depression experiment, you will calculate the colligative molality of the solutions you produce, the freez
ing point depression, and the predicted boiling point of the resulting solutions. This question will give you practice doing this before you come to lab. In an experiment, you use 8.600 g of solvent (FP = 94.3°C; Kf = 5.2°C/m) and 0.750 g of solute (molecular mass = 163.78 g/mol). (a) How many moles of solute have you used? WebAssign will check your answer for the correct number of significant figures. mol (b) What is the colligative molality of the solution formed? WebAssign will check your answer for the correct number of significant figures. m (c) What is the predicted freezing point depression ΔTf? WebAssign will check your answer for the correct number of significant figures. °C (d) What is the predicted freezing point of the solution formed?
Electrons in n=1 are strongly attracted to the nucleus and therefore will require great force to overcome the electrostatic force of attraction to displace them from the energy level to another.
The electrostatic force reduces as you progress to the outer energy levels.
