I don't see a table.
1. (KOH) = mols/L
mols = 1.4 g/molar mass = ?
Then mols/dm3 = M = ?mols from above/0.250 L = ?
Did you use 25 cc H2SO4? How much KOH was used in the titration?
A is a solution of tetraoxosulphate (vi) acid, B is a solution containing 1.4g of potassium hydroxide per 250cm3.
using the table above as the value for your titration and 25cm3 for the value of pipette used
1. concentration of B in mol/dm3
2. concentration of A in mol/dm3 3. number of hydrogen ion in 1.0dm3 of A?
