Question

Calculate the mass of H2SO4 present in a decinormal solution

Answer 1

Dear Student, It is given that: Normality = 0.1 N Molar mass of sulphuric acid = 98 g/mol. Valency of sulphuric acid = 2 pls mark brainliest

Answer 2

The mass of H2SO4 present in a decinormal solution is 4.9 gm

- It is given that the H2SO4 solution is decinormal.

⇒ Normality of solution = N/10 = 0.1 N

- For H2SO4

M.wt = 98 gm

n = 2

- We know that

N = n × M

M = 0.1 / 2 = 0.05 M

⇒ 0.05 moles of H2SO4 are present in 1 litre solution

⇒ Mass of H2SO4 = 0.05 × 98 = 4.9 gm
