123. Solving a chemistry problem
A solution of 2.7350 g of sodium carbonate was prepared in a 200 ml volumetric flask. Titration of 20.00 ml of the resulting solution in the presence of methyl orange consumes 18.65 ml of HCl (T = 0.003854). Calculate the % water content in the sample, if it is known that it does not contain foreign impurities in noticeable quantities. How many % more or less water is in the sample compared to the exact decahydrate crystalline hydrate?
