The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
2 moles of Ca and 4 moles of OH
CaOH2 is a base because calcium is compounded with hydroxide, rather than hydrogen. Most if not all acids' names begin with 'H', while most if not all bases' names end with 'OH'.
There are a total of 118 elements known to exist on the periodic table.

Ca(OH)2 and Na2O
The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
2 moles of Ca and 4 moles of OH
Yes, Ca(OH)2 is a strong base. When it dissolves in water, it releases hydroxide ions (OH-) which can accept protons to form water, making the solution basic.

The molecular weight of Ca(OH)2 (calcium hydroxide) is approximately 74.09 g/mol.
Calcium hydroxide is written as Ca(OH)2 because the hydroxide ion (OH-) is a polyatomic ion composed of one oxygen atom and one hydrogen atom. In the compound, there are two hydroxide ions associated with one calcium ion, which is why it is written as Ca(OH)2 and not CaOH2.
