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?
