Calcium hydroxide contain calcium, hydrogen and oxygen.
2 moles of Ca and 4 moles of OH
The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
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.
The current periodic table contains 118 elements, as of April 2010, but many more may still be discovered.
Nope... it is not.

In one mole of this solution, there are seven moles of H2O.
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
Calcium Hydroxide, or CaOH2, is a base. Generally compounds containing hydroxyl groups and metals will act as bases in reaction.

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.
