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
There are a total of 13 atoms in 3Fe(OH)3. This includes 3 iron (Fe) atoms, 9 oxygen (O) atoms, and 3 hydrogen (H) atoms.
There are a total of 3 nitrogen atoms in the formula Al(NO3)3.
There are a total of 17 atoms in 3H3PO4. This includes 3 hydrogen atoms, 3 phosphorus atoms, 12 oxygen atoms, and 1 carbon atom.
15 Fe2O3 has 2 + 3 atoms = 5 atoms Multiply the whole thing by 3 and you end up with 15 atoms.
It has 4 oxygen atoms.
Nope... it is not.
3 atoms I think.
In one mole of this solution, there are seven moles of H2O.
2 moles of Ca and 4 moles of OH
There are 3 atoms of sulfur in Al2(SO4)3.
7 atoms
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
Calcium hydroxide.
There are a total of 13 atoms in 3Fe(OH)3. This includes 3 iron (Fe) atoms, 9 oxygen (O) atoms, and 3 hydrogen (H) atoms.
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
There are a total of 3 nitrogen atoms in the formula Al(NO3)3.
There are 3 atoms of sulfur, 9 atoms of oxygen, and 2 atoms of iron in Fe2(SO4)3, making a total of 14 atoms.
