Well we can quote the elemental composition...........

Explanation:

"% composition"="Atomic mass"/"Molecular mass"xx100%% composition=Atomic massMolecular mass×100%

%H=(3xx1.00794*g*mol^-1)/(97.99*g*mol^-1)xx100%=3.1%.%H=3×1.00794⋅g⋅mol−197.99⋅g⋅mol−1×100%=3.1%.

%P=(30.9737*g*mol^-1)/(97.99*g*mol^-1)xx100%=31.6%.%P=30.9737⋅g⋅mol−197.99⋅g⋅mol−1×100%=31.6%.

%O=(4xx15.999*g*mol^-1)/(97.99*g*mol^-1)xx100%=65.3%.%O=4×15.999⋅g⋅mol−197.99⋅g⋅mol−1×100%=65.3%.

Do the elemental percentages sum up to 100%100%? Should they?
