How do molecular mass and the concentration of a solute affect the freezing point of a solution?

Question

Which of the following has the greatest effect on freezing point?

a.) higher concentration and lower molecular masses have the greatest effects.

b.) lower concentration and lower molecular masses have the greatest effects.

c.) higher concentration and higher molecular masses have the greatest effects.

d.) lower concentration and higher molecular masses have the greatest effects.

Answer 1

a is correct answer since the freezing point depression is proportional to the molarity which is proportonal to concentration and inversely related to molecular mass
