Izin mengoreksi mungkin yang dimaksud adalah Ca3(PO4)2.
Jawaban: 310 gram/mol

Mr adalah massa molekul relatif yang nilainya diperoleh dari total massa atom relatif (Ar) penyusun molekul tersebut. Nilai Ar dapat diperoleh dari nomor massa atom yang tertera pada sistem periodik unsur.

Jika diketahui nilai Ar C= 40, P= 31, dan O= 16, maka Mr Ca3(PO4)2

Mr Ca3(PO4)2= 3(Ar Ca) + 2(Ar P) + 8(Ar O)
Mr Ca3(PO4)2= 3(40) + 2(31) + 8(16) gram/mol
Mr Ca3(PO4)2= 120 + 62 + 128 gram/mol
Mr Ca3(PO4)2= 310 gram/mol

Jadi, nilai massa molekul relatif (Mr) dari Ca3(PO4)2 adalah 310 gram/mol.
