What is the molar mass of calcium hydroxide?

Answer 1

Ellie Andrews

Well, you should look that up and tell me. Isn't it #"74.093 g/mol"#?

#M_(Ca(OH)_2) = M_(Ca) + 2[M_(O) + M_(H)]#

#= "40.078 g/mol" + 2["15.999 g/mol" + "1.0079 g/mol"] = ???#

The molar mass of calcium hydroxide (Ca(OH)2) is calculated by adding up the atomic masses of each element in the compound. The molar mass of calcium (Ca) is approximately 40.08 g/mol, the molar mass of oxygen (O) is approximately 16.00 g/mol, and the molar mass of hydrogen (H) is approximately 1.01 g/mol. Therefore, the molar mass of calcium hydroxide is approximately 40.08 + (16.00 × 2) + (1.01 × 2) = 74.14 g/mol.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
