With the help of the above formula, if we know the molarity (concentration) of a solution and the total volume of the solution in litres, we can determine the number of moles of solute. Then the mole of solute is converted to grams....
1X PBS: 137 mM NaCl 2.7 mM KCl 20 mM KH2PO4 You calculate this in the following manner: For example 10X PBS Given: MW NaCl 58.44, that is 58.44 g in 1 L = 1 M (58.44 g/L), your desired molarity 1.37 M in 1 L 58.44 g/L x 1.37 M = 80 g in 1 L Given MW KCl 74.55...

molality is approximately equal to molarity for dilute aqueous solutions at this temperature. This is a useful approximation, but remember that it is only an approximation and doesn't apply when the solution is at a different temperature, isn'...
