I can easily work out the molar mass of Ca3PO4 - but I do not see any reason to do this.

There is no such compound

If you want the molar mass of tricalcium phosphate , then the correct formula is Ca3(PO4)2 .

For purposes of calculating the molar mass it is easier to write: Ca3P2O8

Ca = 40.078g/mol *3 = 120.234g

P = 30.974g/mol *2 = 61.948g

O = 15.999g/mol *8 = 127.992g

Total = 310.174g/mol

Mass of 4.5 mol = 310.174g/mol *4.5mol = 1395.783g
