Answer 2

Hey Dear,

◆ Answer -

(2) 1.0 N

◆ Explanation -

When the solution is diluted, weight of H2SO4 remains same, just the volume of solution is increased.

Gram equivalent of H2SO4 is calculated as -

Gram equivalent = given weight / equivalent weight

Gram equivalent = 490 / 49

Gram equivalent = 10

Normality of the solution is calculated by -

Normality = Gram eq. of solute / Volume of soln

Normality = 10 / 10

Normality = 1 N

Therefore, normality of the soln is 1 N.

Hope this helped you.
