Question

What is the molar mass of calcium hydroxide?

Answer 1

The molar mass of calcium hydroxide, `"Ca(OH)"_2"`, is `"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: `"Ca(OH)"_2`

Molar Mass `"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`
