Answer:
The molecular formula of calcium hydroxide is =Ca(OH)2 .
Its molecular mass is =40+(16+1)×2=40+17×2=74u
The expression for the equivalent weight of Ca(OH)2 is as given below.
Equivalent weight =
Molecular mass/No. of replaceable OH groups
Calcium hydroxide contains two replaceable OH groupsSubstitute values in the above expression.
Equivalent weight =74u/2 =37u
