Calculate the number of oxialic acid molecules in `100 mL` of `0.02 N` oxialic acid

Explanation

`:'` Normality = 0.02
`:.` Molarity `= (0.02)/(2)` ` ( :'` Valency factor = 2)
`:.` Moles of oxalic acid `= (0.02)/(2) xx (100)/(1000)`
`( :. "Moles" = M xx V_(1))`
`:.` Number of molecules of oxalic acid
`= 0.001 xx 6.023 xx 10^(23)`
`= 6.023 xx 10^(20)`
