The number of atoms is 33.
44 moles of atoms
In 3Ca(OH)2 there are three Ca(OH)2 - (Calcium hydroxide) moleculesIn one Ca(OH)2 there is one Calcium, and two (OH) units. In one (OH) unit there is one Oxygen and one Hydrogen. With the above information it evident that there are 5 atoms in one Ca(OH)2 molecule and as there are 3 of these molecules present, there would be a total of 15 atoms present in 3Ca(OH)2
