2 NaOH + H2SO4 ---> Na2SO4 + 2 H2O
5 kmoli H2SO4 = 5*98 kg = 490 kg acid
2*40 g NaOH.......98 g H2SO4
x kg NaOH..........490 kg H2SO4        x = 400 kg NaOH
c%=md/ms*100=>ms=400/20*100=2000 kg solutie NaOH
2*40 g NaOH.........98 g H2SO4
2000 kg sol NaOH.........x kg solutie H2SO4
x = 2450 kg solutie H2SO4
