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.
What is the molar mass of the sodium hydroxide? - Vedantu
WebEnter a chemical formula to calculate its molar mass and elemental composition: ... Compound name is sodium hydroxide. Convert between NaOH weight and moles. … WebOct 10, 2024 · 0.1 moles/liter x 0.25 liters = 0.025 moles NaOH needed. The molar mass of NaOH is 23 + 16 + 1 = 40 g/mole. Thus, 0.025 moles NaOH x 40 g/mole = 1 gram NaOH. To make 250 ml of 0.1 M NaOH, you dissolve 1 gram NaOH in enough water to make a final volume of 250 mls. Upvote • 0 Downvote. iron besylate
