Answer:
Chemical Formula = Ca(OH)₂
Molar Mass = 74.09 g/mol
Explanation:
The chemical formula for calcium hydroxide is: Ca(OH)₂. We can know that because the calcium ion always has a +2 charge, while the hydroxide ion has a -1 charge.
We calculate the molar mass by adding together the atomic masses of each atom that makes the compound (these can be found in a periodic table):
Molar Mass = Atomic Mass Ca + (Atomic Mass O)*2 + (Atomic Mass H)*2
Molar Mass = 40.078 + (15.999)*2 + (1.007)*2
Molar Mass = 74.09 g/mol
