Answer to Question #153423 in General Chemistry for Aman

Question

Calculate mass of Al2(so4)3 in 250 ml of solution if the concentration is 0.48 N.

Answer 1

Normality = no. of equivalent/volume of solution

0.48N = (No. of equivalent/0.25L)

no. of equivalent = 0.12

no. of moles / n-factor = 0.12

no. of moles = 0.12× 3 = 0.36

mass/molar mass = 0.36

mass = 0.36×342 = 123.12gram
