Question

calculate the maniculas weight equlent weight CAOH
​

Answer 1

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
