Molar mass of Al(OH)3 =

78.01 g/mol

Explanation:

To find the molar mass of Al(OH)₃, we have to look at the mass of each individual element on the periodic table.

Al - 26.98

O - 3(16.00) = 48.00

H - 3(1.01) = 3.03

Now add it all together.

26.98 + 48.00 + 3.03 = 78.01 or 78 g/mol

Hope that helps.
