A solution was prepared by dissolving 2.6061g of sodium carbonate in distilled water and making it up to 250cm3. A 25cm3 portion of the solution was titrated against hydrochloric acid. The equivalence point was reached when 18.7cm3 of the acid was added. Calculate the concentration of the hydrochloric acid in mol dm-3 and g dm-3.

i think a, hope it .
