Question

determine the molar mass of ca(oh)2. provide an answer to two decimal places.

Explanation:

Step1: <Calculate molar mass of Ca>

The molar mass of \( Ca \) is \( 40.08\ \text{g/mol} \).

Step2: <Calculate molar mass of O>

There are \( 2 \) O atoms. Molar mass of \( O \) is \( 16.00\ \text{g/mol} \), so for \( 2 \) O: \( 2\times16.00 = 32.00\ \text{g/mol} \).

Step3: <Calculate molar mass of H>

There are \( 2 \) H atoms. Molar mass of \( H \) is \( 1.01\ \text{g/mol} \), so for \( 2 \) H: \( 2\times1.01=2.02\ \text{g/mol} \).

Step4: <Sum up the molar masses>

Molar mass of \( Ca(OH)_2=40.08 + 32.00+2.02\)
