Iridium (IV) phosphate
The name of this compound is zinc phosphide.
The compound Ca3 PO4 is called Calcium Phosphate.
Pb3(PO4)4
To find the percent composition of phosphorus in Zn3(PO4)2, calculate the molar mass of PO4 (phosphate) first. The molar mass of PO4 is 1 * P (phosphorus) + 4 * O (oxygen). Then, divide the molar mass of P by the molar mass of the entire Zn3(PO4)2 compound and multiply by 100 to get the percentage.
The chemical formula for phosphate is PO4^3-.
The name of the compound Pb3(PO4)4 is lead(IV) phosphate.
Tin(IV) phosphate
The chemical name for Zn3(PO4)2 is zinc phosphate.
The name of Hg3(PO4)2 is trimercury diphosphate.
PO43- is the phosphate ion.
The chemical name for Mg3(PO4)2 is magnesium phosphate.
The correct name for Sr3(PO4)2 is strontium phosphate.
The correct name for S3(PO4)2 is trisodium diphosphate.
Mo3(PO4)4
phospate
I believe that what you have in mind is the phosphate radical, PO4. While this radical appears in many compounds, it is not itself a compound.
The chemical formula Sr3(PO4)2 is for strontium phosphate.
