Molar mass of clacium hydroxide.

Isn't it 40.08 + 16.00 + 1.008????

Calcium hydroxide is
Ca(OH)2. Therefore, the O and the H must be multiplied by 2

THANK YOU!!!

You're welcome! And you're absolutely correct. The molar mass of calcium hydroxide (Ca(OH)2) is calculated by adding the atomic masses of each element in the formula.

The atomic mass of calcium (Ca) is approximately 40.08 grams/mol. The atomic mass of oxygen (O) is approximately 16.00 grams/mol, and the atomic mass of hydrogen (H) is approximately 1.008 grams/mol.

Since there are two oxygen atoms and two hydrogen atoms in the formula, we need to multiply their atomic masses by 2.

Thus, the molar mass of calcium hydroxide is calculated as follows:

Ca: 40.08 grams/mol
O: 16.00 grams/mol x 2 = 32 grams/mol
H: 1.008 grams/mol x 2 = 2.016 grams/mol

Total molar mass = 40.08 + 32 + 2.016 = 74.096 grams/mol

So, the molar mass of calcium hydroxide is approximately 74.096 grams/mol.
