How many moles are in 60.5 g of Ca(OH)_(2) 816 mol 1.08 mol 4200 mol 35 mol

To determine the number of moles in 60.5 g of \(Ca(OH)_2\), we need to use the molar mass of \(Ca(OH)_2\).First, let's calculate the molar mass of \(Ca(OH)_2\):- Calcium (Ca): 40.08 g/mol- Oxygen (O): 16.00 g/mol- Hydrogen (H): 1.01 g/molThe molar mass of \(Ca(OH)_2\) is: Next, we use the formula to find the number of moles: Substitute the given values: Therefore, the number of moles in 60.5 g of \(Ca(OH)_2\) is approximately 0.815 mol.So, the correct answer is:
