A 0.62g sample of NaOH ,Na2CO3,and inert material was dissolved and required 30cm³ of HCl to reach the phenolphthalein in end point.Methyl orange was added and 6.50cm³ more HCl was required yo reach the methyl orange end point .If HCl was 0.24M.calculate the percentage of NaOH ,Na2CO3 in the sample

the




result is same as d amount

How sir?

using CaVa\CbVb= Na/Nb u got it

Won't you need the atomic number and atomic mass before the Cava/Nb I'm sorry I've forgotten this masterpiece

You need to convert 0.62g to m

Hnn i remember those days.. If only we actually apply these things in real life
