Jul 29, 2017. 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.
Step 1. It has 2 H , 1 S and 4 O atoms. Atomic mass of H is 1.008 g / m o l . Atomic mass of S a n d O is 32.065 g / m o l a n d 16.00 g / m o l respective... Match each compound with its correct molar mass. 74.09 H2SO4 g/mol Ca (OH)2 IIII 98.08 g/mol CuSO4.5H20 K3PO4 212.27 g/mol 33 249.68 g/mol.
