Q. For dilute solutions, the relation between molality (m) and mole fraction of solute (X₂) is approximately:

तनु विलयनों के लिए, मोललिटी (m) और विलेय के मोल अंश (X₂) के बीच संबंध लगभग है:

X₂ = m
एक्स₂ = एम

X₂ = m/(m+1000/M₁)

X₂ = m × M₁/1000

X₂ = M₁/1000 × m
X₂ = M₁/1000 × मी

For dilute solutions:
$X_{2} \approx \frac{m \times M_{1}}{1000}$

where $M_{1}$ is the molecular weight of the solvent.

This relates mole fraction to molality through solvent molecular weight.
