To completely neutralize a 0.325 g sample of pure aspirin, 15.50 ml of a sodium hydroxide solution is added. if 16.25 ml of the same sodium hydroxide solution must be added to an aspirin tablet sample during a titration to reach the endpoint, calculate the mass of aspirin in the table

a. 0.310 g
b. 0.288 g
c. 0.392 g
d. 0.450 g
e. 0.341 g

The correct option is E.

Explanation: The reaction between aspirin (also known as acetylsalicylic acid) and sodium hydroxide is known as acid-base titration reaction.

By applying Unitary method, we get:

15.50mL of NaOH dissolves = 0.325 g of aspirin

So, 16.25 mL of NaOH will dissolve = = 0.341 g

Hence, the correct option is E.
