- Molarity is concentration of a substance that is calculated as the number of moles of solute that is dissolved in 1 liter of solution while molality is concentration of a substance that is calculated as the number of moles of solute found in 1 kg of solvent.
- The symbol for molarity is M, while that for molality is m (sometimes written as -m or m to distinguish it from mass).
- The formula for molarity is moles / liter while the formula for molality is moles / kg.
- Molarity is affected by changes in temperature while molality is unaffected by changes in temperature.
- Molarity is affected by changes in pressure while molality is unaffected by changes in pressure.
- Molarity may result in an imprecise and inaccurate concentration, while molality results in an accurate precise measurement of concentration.
