Question

the normality of 4.9 % (w/w) H2SO4 solution having density 1.02 g/ ml​

Answer 1

hey mate!!

__________________⭐

4.9% w/w H2SO4 means

4.9g H2SO4 in 100ml solution

find molarity

m = (4.9 × 1000) / (98×100)

m= 0.5

then, find normality by multiplying molarity by valency factor.

valency factor for H2SO4 is 2
