If we know molality then how to calculate molarity

Answer»

know the moles of solute and the amount of SOLUTION, you just divide them. For EXAMPLE, if you have 0.5 moles of NaCl in 1.5 L of H2 O, the molarity is 0.5 / 1.5 L. M = 0.33 M. If you don't know the moles but you have the mass, you can still FIGURE outthe molarity by using the mole ratio.
