Answer:

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#
