Problem 106

Given information

Given:

All the substances given to us costs the same amount per kilogram.

Substances are:

a.   

b.  

c.  

d.  

e. 

Step-by-step explanation

The colligative property is a decrease in the freezing point of a solvent. The amount of moles of solute present in the solution determines this. The number of moles of solute present in a solution is determined by the number of ions dissociated by a specific substance and the molecule's molar mass. The larger the number of moles of solute present in the same mass of the solute, the lower the molar mass of the compound. As a result, the molecule with the most ions in solution and the lowest molar mass effectively lowers the freezing point of water.
