Moles of solute per kilogram of solvent.
Unlike molarity, molality is based on the mass of solvent rather than the total solution's volume — this makes it independent of temperature, since mass doesn't change as liquids expand or contract with heat.
Boiling point elevation and freezing point depression calculations specifically require molality rather than molarity, precisely because those effects need a temperature-independent concentration measure.
Molar mass of any chemical formula (e.g. H2O, C6H12O6, Ca(OH)2).

What you entered
Moles = mass ÷ molar mass
58.5 ÷ 58.44= 1.001 molMolality = moles ÷ kg of solvent
1.001 ÷ 1= 1.001 mol/kgResult
Molality: 1.001 mol/kg
This solution has a molality of 1.001 mol/kg (m).
