0.500 cm3 of concentrated H2O2 solution diluted exactly to 50.00 cm3 by water. 10.00 cm3 samples were taking out, and titrated by 0.02003 mol/dm3 KMnO4. The average of the individual result is 18.15 cm3. Give the molarity (mol/dm3) and the mass concentration (g/dm3) of the original concentrated H2O2 sample! Mr = 34.02 g/mol.

Answer :- Molarity (mol/dm3) of original concentrated H2O2 sample = 9.09 mol/dm3 Mass…

Answered: 0.500 cm3 of concentrated H2O2 solution…
