Determine the molarity of a sodium hydroxide solution? if 37.34 mL of it are required to neutralize 1.922 g of citric acid.
balanced equation- 3NaOH(aq)+H3C6H5O7-->3H2O(l)+NaC6H5O7(aq…
***Plesae show steps.
You made a typo in the equation. It should be Na3C6H5O7(aq) on the right.
moles citric acid = grams/molar mass
Convert moles citric acid to moles NaOH. From the equation you can see that 3 moles NaOH = 1 mol citric acid; therefore, mols NaOH = 3 x moles citric acid.
Then M NaOH = moles NaOH/L NaOH
