Question

calculate normality and mortality when 4.9 gram H2 S o4 dissolved in H2O make 250 ml solution​

Answer 1

Answer:

Morality = 0.2M, Normality = 0.1N

Explanation:

Mass Of H₂So₄ = 4.9 Grams

Moles Of H₂So₄ = 1/20

Volume Of Solution = 250 ml = 1/4 l

Hence,

Morality = (No. Of Moles Of Solute) / Volume Of Solution

             = ( 1/20 ) / ( 1/4 )

             = 1/5

             = 0.2 M

Normality =  n factor × Morality    

                = 1/2 × 0.2

                = 0.1 N
