Given :

A student titrates 0.2087 g of an unknown diprotic acid with 0.1224 M sodium hydroxide.

It takes 32.47 mL of the NaOH solution to reach the endpoint.

To Find :

How many moles of NaOH are used in the titration.

Solution :

Number of moles( n ) is given by :

n = Molarity × Volume( in liters )

n =

n = 0.00397 moles.

Therefore, moles of NaOH are used in the titration is .

its first and third is your answer i did the qustion the fourth isnt right

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
