Answer:

The equivalent weight of calcium hydroxide is 1/2 he mass of a mol of calcium hydroxide. 1 mol Ca(OH)2 = 74 grams Ca(OH)2 ; 1 equivalent Ca(OH)2 = 37 grams Ca(OH)2.

Answer:

The gram equivalent mass of calcium hydroxide is 37g.

Explanation:

The molecular formula of calcium hydroxide is Ca(OH)₂.

The atomic weights of calcium, oxygen, and hydrogen are 40u, 16u, and 1u.

Therefore, the molecular mass of Ca(OH)₂ is 40+(16+1)×2 = 40+34 = 74u.

The equivalent mass is given as the ratio of molecular mass to the number of replaceable hydroxyl groups.

Equivalent mass = Molecular mass / Number of replaceable hydroxyl group

Equivalent mass = 74/2 since there are two -OH groups in calcium hydroxide.

Equivalent mass = 37g.

Therefore, the gram equivalent ass of calcium hydroxide is 37g.
