Question

The ionization constant of sulphuric acid is 1.74x 10 -5 . Calculate the degree of dissociation of sulphuric acid in its 5 M solution. Calculate the concentration of sulphate ions ion in the solution als​

Answer 1

Answer:

The molar mass of H2SO4 is 98.1 (rounded to three SFs), so 9.8 g would equate to 0.0999 mols of H2SO4 (again rounded to three SFs). We can then multiply 0.0999 mols by Avogadro's number (6.02 x 10^23) to find that there are roughly 6.02 x 10^22 molecules of H2SO4 in 9.8g of the compound.
