24. Solving a chemistry problem

7. 25.00 ml of H2SO4 solution was added to a sample of chemically pure CaCO3 weighing 0.1011 g. 9.25 ml of NaOH solution was used for titration of excess acid. Find the concentrations of H2SO4 and NaOH solutions if the ratio of equivalent volumes V(NaOH):V(H2SO4)=0.995.
Answer: C(NaOH)=0.1280 M; С(H2SO4)=0.06368М.
