Question

Calcular la normalidad de 1 Kg de sulfuro de aluminio en 5000 ml de solucion.

Answer 1

Calculate the normality of 1 Kg of aluminum sulfide in 5000 ml of solution.

Normality comes out to be 8.11

Given

• Mass of solute: 1000g
• Volume of solution (V): 5000 ml = 5 liters
• Equivalent mass of solute (E) = molar mass / n-factor

n-factor for $Al_{2}S_{3}$ is 6 and molar mass is 148g

So, on calculating equivalent mass is equal to 24.66g

FORMULAE of Normality (N) = (Mass of the solute) / (Equivalent mass of the solute (E) × Volume of the solution (V)

                                           N=$\frac{1000}{24.66*5}$

                                          N=8.11

Therefore, normality of 1 kg aluminum sulfide is 8.11
