What Is Molality?
Molality is a concentration unit expressing the amount of dissolved substance, in moles, per kilogram of solvent. It is not affected by temperature.
How is it calculated?
How Is It Calculated?
Molality (m) = moles ÷ solvent mass (kg)
- Enter the moles of solute and the mass of the solvent.
Frequently Asked Questions
Why is molality not affected by temperature?
Because it is based on mass, it is not affected by temperature, which changes volume.
