Question

Calculate number of molecules of oxalic acid
in 100ml of 0.2N oxalic acid solution

Answer 1

Answer :

2N for oxalic acid is .1M   (since 1 mole of oxalic acid produces 2 moles of H+ ions) .1M  x  .100 L = .01 moles of oxalic acid  .01 moles  x 6.02 x 1023 molecules/mole  =  6.02 x 1021 molecules
