Question

calculate the normality of Ca(OH)₂ in a solution made by dissolving 4.75 g Ca(OH)₂ in enough water to a make 250 mL of solution

Answer 1

Normality = # equilvalents/L of solution.

#equivalents = grams/equivalent weight.
equivalent weight Ca(OH)2 = molar mass/2
# equivalents = 4.75/equivalent weight = ??
N = ??equivalents/0.250 L = xx

Answer 2

0.512N
