Answer:
(i) The mass concentration of H₂SO₄ is 49 Kg/m³
(ii) The mass flow rate of H₂SO₄ (solution) is 1.02 Kg/s
(iii) The mass fraction of H₂SO₄ is 0.0475.
Explanation:
Given, the concentration of Sulphuric acid solution, C = 0.5 M
The rate of flow, f = 1.25 m³/min
The density of solution, ρ = 1.03 Kg/L = 1030 Kg/m³
We know that molar mass of sulphuric acid = 98g/mol
(i) To calculate the mass concentration of H₂SO₄ in Kg/m³ :-
Mass concentration = C × molar mass of H₂SO₄
(ii) The mass flow rate of H₂SO₄ (solution) in kg/s:-
Mass flow rate = Flow rate × mass concentration
Mass flow rate
(iii) The mass fraction of H₂SO₄:-
Mass flow rate of the solution = Density × flow rate
Mole fraction of H₂SO₄
Mole fraction of H₂SO₄
