  1. 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.
  2. The symbol for molarity is M, while that for molality is m (sometimes written as -m or m to distinguish it from mass).
  3. The formula for molarity is moles / liter while the formula for molality is moles / kg.
  4. Molarity is affected by changes in temperature while molality is unaffected by changes in temperature.
  5.  
  6. Molarity is affected by changes in pressure while molality is unaffected by changes in pressure.
  7.  
  8. Molarity may result in an imprecise and inaccurate concentration, while molality results in an accurate precise measurement of concentration.
