4.5 gms of oxalic acid is required to make a M/20 solution of oxalic acid.
Explanation:
M/20 means 0.05 M
so to prepare 0.05 M solution of oxalic acid,
molecular weight of oxalic acid is 90 gram
so to prepare 1M we need 9O gm of oxaloacetete in 1000 ml of distill water
'x' gms will be needed to make 0.05 M solution
Molarity= no.of moles/volume*1000
no. of moles/ 1000= molarity*volume
= 0.05 moles
so, 0.05 moles will be 4.5 gms
4.5 gms of oxalic acid will be dissolved in distil water and volume made upto 1000ml.
