Question

Which mode of expressing concentration is independent of temperature?

• A. Molality
• B. Percent by mass
• C. Mole fraction
• D. All of these

Answer 1

The correct option is D All of these

The terms which includes volume will be temperature dependent otherwise all are temperature independent as,
Molality$=\frac{massofsolute\times 1000}{molarmassofsolue\times massofsolvent}$ , i.e., independent of temperature.
Mole fraction : The ratio of the number of moles of one component to the total number of all the components present in the solution, is called the mole fraction of that component.
Percentage by mass : The number of grams of solute dissolved in one gram of solution is called mass fraction of the solute.
So, all are temperature independent.
