6.0g of impure and hydrous Na2SO4 were made up to 1dm^3 of solution neutralize 22.20cm^3 of 0.1mol/dm^3 of HCL.calculate:
a)concentration of Na2CO3 in mol/dm^3.
b)concentration of Na2CO3 in gram/dm^3.
c)percentage purity in carbon.
Please check your post. There is something wrong. First the wording is not clear; however,even if it were, there is no way to get Na2CO3 out of Na2SO4.xH2O
