#"% by mass of component"# #=#

#"Mass of component"/"Formula mass of barium phosphate"xx100%#

Explanation:

The formula mass of #Ba_3(PO_4)_2# is #601.92*g*mol^-1#.

If we require the % composition by metal content, the calculation is:

#(3xx137.33*g*mol^-1)/(601.92*g*mol^-1)xx100%# #~=66%#

I have taken the mass of the component and divided it by the molar mass.
