The freezing point of 58.53 g of a pure solvent is measured to be 44.17 ºC. When 2.15 g of an unknown solute (assume the van 't Hoff factor = 1.0000) is added to the solvent the freezing point is measured to be 41.26 ºC. Answer the following questions ( the freezing point depression constant of the pure solvent is 7.77 ºC·kg solvent/mol solute). What is the molality of the solution? m How many moles of solute are present? mol What is the molecular weight of the solute? g/mol

Question
The freezing point of 58.53 g of a pure solvent is measured to be 44.17 ºC. When 2.15 g of an unknown solute (assume the van 't Hoff factor = 1.0000) is added to the solvent the freezing point is measured to be 41.26 ºC. Answer the following questions ( the freezing point depression constant of the pure solvent is 7.77 ºC·kg solvent/mol solute).
What is the molality of the solution?
m
How many moles of solute are present?
mol
What is the molecular weight of the solute?
g/mol
Expert Solution
Step 1
We are given with a data for the depression in freezing point on adding a solute to a pure solvent and we have to calculate the molality of solution, number of moles of solute and hence it's molecular weight.
