Question

give the chemical formula molar mass calcium hydroxide

Answer 1

The chemical formula for calcium hydroxide is \( \text{Ca(OH)}_2 \).

To calculate the molar mass, we will consider the molar masses of its constituent elements:

- Calcium (Ca): approximately 40.08 g/mol
- Oxygen (O): approximately 16.00 g/mol (there are 2 oxygen atoms)
- Hydrogen (H): approximately 1.01 g/mol (there are 2 hydrogen atoms)

Now, we can calculate the molar mass of calcium hydroxide:

\[
\text{Molar mass} = \text{Ca} + 2 \times \text{O} + 2 \times \text{H}
\]
\[
\text{Molar mass} = 40.08 + 2 \times 16.00 + 2 \times 1.01
\]
\[
\text{Molar mass} = 40.08 + 32.00 + 2.02
\]
\[
\text{Molar mass} = 74.10 \, \text{g/mol}
\]

Therefore, the molar mass of calcium hydroxide \( \text{Ca(OH)}_2 \) is approximately \( 74.10 \, \text{g/mol} \).
