How many moles of sodium bicarbonate would be needed to react with all of the theoretical aspirin?

Explanation:

The question is incomplete because the amount of theoretical aspirin is missing.

I can solve with a hypothetical amount of aspirin (acetylsalicylic acid).

The chemical formula of acetylsalysilic acid is C₉H₈O₄.

Assume 325mg of pure acetilsalysilic acid.

There is one carboxylic acid group in the molecule of acetylsalicylic acid.

Sodium bicarbonate is NaHCO₃.

Then, 1 mole of NaHCO₃ will react with 1 mole of C₉H₈O₄.

Hence, the mole ratio for the reaction between sodium bicarbonate, NaHCO₃, and aspiring, C₉H₈O₄, will be 1 : 1.

Find the number of moles of C₉H₈O₄ in 325mg.

Then, as the theoretical mole ratio is 1 : 1, the same amount, 0.00180 moles of sodium bicarbonate, would be needed to react with all of the theoretical aspirin.

the answer is option a.
