7. A sample of sodium bicarbonate weighing 0.9990 g was dissolved in 20 ml of freshly boiled and cooled water. To titrate the resulting solution, 25.10 ml of 0.5 M HCl (K = 0.9980) was consumed. Calculate the mass fraction of NaHCO3 (Mr 84.01) in the sample. Does the mass fraction of NaHCO3 in the sample meet the requirements of the State Fund (at least 99.0%).
