MCQ
What does not change on changing temperature
- AMole fraction
- BNormality
- CMolality
- ✓Both $(a)$ and $ (c)$
✓
Answer
Correct option: D.
Both $(a)$ and $ (c)$
d
Molality is given by $m =$
Molality is given by $m =$
$\frac{ n _{\text {solute }}}{ W _{\text {solvent }}} W _{\text {solvent }}$ is the mass of solvent which is independent of temperature.
Normality is given by $N =\frac{ n _{\text {eq }} \text { of solvent }}{ V _{\text {solution }}}$
Here, it is dependent on volume which is temperature-dependent.
Mole fraction is dependent on the amount of substance which is temperature independe:
Therefore, Molality and mole fraction are temperature independent.
