Answer:

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

Explanation:

#"% composition"="Atomic mass"/"Molecular mass"xx100%#

#%H=(3xx1.00794*g*mol^-1)/(97.99*g*mol^-1)xx100%=3.1%.#

#%P=(30.9737*g*mol^-1)/(97.99*g*mol^-1)xx100%=31.6%.#

#%O=(4xx15.999*g*mol^-1)/(97.99*g*mol^-1)xx100%=65.3%.#

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