Answer 2

Answer:

C) 2.4 L

Explanation:

Given,

Morality of solution, H2SO4 = 3 Molar

Volume of solution, H2SO4 = 4 Litre = 4000ml

We Know that,

Mass of H2SO4 = 98 g

% w/v = mass of solute / volume of solution × 100

% w/v = 98 / 4000 × 100

% w/v = 98 / 40

% w/v = 2.45 g ml^-1

Therefore, Option C is correct.
