Determine the molar mass of naoh

WebFor instance, you can find the molar mass of an acid by titrating the acid with a solution of base of known concentration. e.g. What is the molecular weight of an unknown monoprotic acid if 0.4955 g of the acid are neutralized by 37.00 mL of a 0.1000 M NaOH solution? WebThen to determine the molar mass, the calculation is as follows: 7.72 g HA 1L soln L soln 0.12 mol = 64.33 mol 64-8 HA A technique known as half-titration can now be used to determine the pk of the weak acid. In this experiment, the half-titration point will exist when you have added half the volume of NaOH needed to fully titrate the acid.
