Question

what is the molar mass of this compound? ca(oh)₂ remember to round to the hundredths place from the periodic table. 57.09 g/mol 74.00 g/mol 74.10 g/mol 34.02 g/mol

Explanation:

Step1: Find the atomic masses

From the periodic table, the atomic mass of \(Ca\) (calcium) is \(40.08\space g/mol\), the atomic mass of \(O\) (oxygen) is \(16.00\space g/mol\), and the atomic mass of \(H\) (hydrogen) is \(1.01\space g/mol\).

Step2: Calculate the molar mass of \(Ca(OH)_2\)

The formula \(Ca(OH)_2\) has 1 \(Ca\) atom, 2 \(O\) atoms, and 2 \(H\) atoms.
The molar mass \(M\) is calculated as:
