Question

Calculate the mass of Naoh containing 50 ml of N/10 Naoh solution

Answer 1

Answer= m=0.2grams

Explanation:

normality= mass of solute/molecular mass×1000ml/given volume of solution

          1/10=m/40×1000/50

            1/10×40×50=m×1000

             200=m×1000

               m=200/1000

                 m=1/5grams

                  m=0.2grams
