Question

Which of the following do/does not change with the change in temperature?

i. Mole fraction.

ii. Molality.

Select one:
a. only i
b. Only ii
c. Both i & ii
d. Neither of them
(I did D and it was incorrect)

Answer 1

c. Both i & ii

Step-by-step explanation:

Moles do not change with temperature hence Mole fraction does not depends of temperature.

Molality is number of moles of solutes per kilogram of solvent. It has no relationship with temperature.

This means both of them do not change wit the change in temperature.

Correct option;

c. Both i & ii
