How do you go about solving this?
Homework Answers
m = 3 kg solvent
Kf = -1.86
m = mol s /kg solvent
dTf = 0-13 = -13
then
dTf = -Kf*m
-13 = -1.86*m
m = 13/1.86 = 6.989247 mol per kg solvent
m = 3 kg so
molality = mol/kg
6.989247*3 = mol
mol = 20.967741 mol of sorbitol max
mass = mol**MW = 182.17 *20.967741 = 3819.6 g of sorbitol

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...
