Question

4.2 gram any 2 s o4 is dissolved in 400 ml water find out formality and normality of solution

Answer 1

Answer:

molarity= 0.25M

normality= 0.5N

Explanation:

molarity= (weight of solute/molecular mass of solute)/(volume of solution/1000)

(14.2/142)/(400/1000)

= 1/4 0.25M

normality= molarity*valency

=0.25*2

= 0.5N
