Potassium hydroxide reacts completely with sulfuric acid according to the equation:

H2SO4(aq) + 2KOH(aq) K2SO4(aq) + 2H2O(l)

0.95 g of potassium hydroxide were dissolved in water and made up to 250 cm3 of
solution. 25 cm3 samples of this solution were titrated against sulfuric acid (H2SO4)solution. The mean volume (titre) of sulfuric acid required for complete reaction was15.00 cm3.

hydroboration of styrene followed by oxidation with hydrogen peroxide leads to the formation of compound A. oxidation of styrene with potassium permanganate in an acidic medium results in compound B. Compound A and B can react with each other under acidic catalysis to form compound C . what is the volume of carbon dioxide ( molar volume of ideal gas Vm = 22.4 l/mol) , released during the complete combustion (In excess of oxygen) of 5.0 grams of compound C?
