Question

A solution of glucose received from some research laboratory has been marked mole fraction x and molality (m) at $10^{\circ }C$. When you will calculate its molality and mole fraction in your laboratory at ${24}^{\circ }C$ you will find:

• A. mole fraction (x) and molality (m)
• B. mole fraction (2x) and molality (2m)
• C. mole fraction (x/2) and molality (m/2)
• D. mole fraction (x) and (m${}_{-}^{+}$dm) molality

Answer 1

The correct option is A mole fraction (x) and molality (m)

Molality and mole fractions both are independent of temperature . Therefore they will remain same after change of temperature.
