molality to molarity
Please provide values below to convert molality [mol/kg] to molarity [mol/L], or change ↔.
molality [mol/kg]
Definition: Molality (mol/kg) is a unit of concentration used in chemistry, defined as the number of moles of solute per kilogram of solvent.
Historyandorigin: Molality was introduced to avoid the effects of temperature on volume, which can cause variations in molarity.
CurrentUse: It is especially useful in studying colligative properties like freezing point depression and boiling point elevation, which depend on solvent mass.
funfact: Molality remains constant even when temperature changes, unlike molarity, which can vary with temperature due to changes in volume!
molarity [mol/L]
Definition: Molarity (mol/L) is a unit of concentration used in chemistry, defined as the number of moles of solute per liter of solution.
Historyandorigin: The unit of molarity was introduced by Gilbert N. Lewis in the early 20th century to quantify the concentration of solutions.
CurrentUse: It is widely used in laboratory settings for preparing and diluting chemical solutions, particularly in acid-base titrations and reactions.
funfact: A 1 M solution contains one mole of solute in exactly one liter of solution!

How to Convert molality to molarity
1 molality [mol/kg] = 0.9990209595 molarity [mol/L]
1 molarity [mol/L] = 1.00098 molality [mol/kg]
we use cross multiplication method
molality [mol/kg] → molarity [mol/L]
1 → 0.9990209595
1.5 → ?( suppose x)
=>1.5*0.9990209595=1*x
by simplifying
x=1.4985314392
