(Answered) A 0204-g sample of a co32- antacid is dissolved with 250 ml

Academics

A 0.204-g sample of a CO3^2- antacid is dissolved with 25.0 mL of 0.0981 M HCl. The hydrochloric acid that is not neutralized by the antacid is titrated to a bromophenol blue endpoint with 5.83 mL of 0.104 M NaOH.

Calculate the number of moles of base in the antacid.
