# What is the molar mass of calcium hydroxide?

Jul 29, 2017

The molar mass of calcium hydroxide, $\text{Ca(OH)"_2}$, is $\text{74.092 g/mol}$.

#### Explanation:

The molar mass of a compound is determined by multiplying the subscript of each element in the formula by its molar mass (atomic weight on the periodic table) in g/mol, and adding the results.

The formula for calcium hydroxide is: ${\text{Ca(OH)}}_{2}$

Molar Mass $\text{Ca(OH)"_2} :$

(1xx40.078"g/mol Ca")+(2xx15.999"g/mol O")+(2xx1.008"g/mol H")="74.092 g/mol Ca(OH)"_2
