So I just finished a chemistry test today and I know I answered this question incorrectly. Could anyone show me the proper way of doing it?

Q. How many atoms of oxygen are in 198.00 g of Ca3(PO4)2?

I only found the number of atoms in total and did nothing to find the number of oxygen atoms. Any help would be great!
