The most common isotopic mass of the phospate group, PO3, is 79. The second most common isotopic mass is incredibly rare, but is 78.
--------------------------------
Phosphate (PO4)3- has not an isotopic mass because it is not an isotope but it is an anion. The mass of this anion is 94,953 42.

What element has the isotopic mass of 209?
Po
Which gas is heaviest nitrogen hydrogen or oxygen?
Isotopic mas of hydrogen ia '1' Isotopic mass of nitrogen is '14' Isotopic mass of oxygen is '16' It follows that oxygen is the n=heaviest of these gases.
How do you calculate isotopic masses?
The atomic mass of isotopes is determined by mass spectrometry.
What relationship exist between the atomic mass and the isotopes?
When atomic mass is expressed in unified atomic mass units, it is similar to isotopic mass and has the same numerical value as that of atomic mass. The atomic mass or the relative isotopic mass is the mass of one atom which at a time can be only one isotope.
What is the mass percent of hydrogen in ammonium phosphate?
The percentage of H in ammonium phosphate is the mass of H divided by the mass of the entire compound.
What is the atomic mass of phosphate?
if you mean phosphorus then the atomic mass is 30.973762. i don't think phosphate is an element.
How is average weight of atomic mass computed?
the average atomic mass is computed by summing all isotopic weights of the isotopes of that element and then dividing this by the the total number of isotopes of that element (note that isotopic mass is exactly the same as atomic weight, except for isotopes).
How do you determine when isotopes are most abundant?
Isotopic composition is determined by mass spectrometry.
What is the average atomic mass of the element with the isotopic abundances shown?
90.7 amu
What mass of phosphorus is contained in 45.3 g of ammonium phosphate?
45.3g/Mmass phosphate x 4mol PO4/1mol x molar mass of ammonium phosphate
What is meant by isotopic effect?
the variton of transition temperature with respect to mass of iostopic electrons
What is the atomic mass of B if 19.9 percent of all B atoms have a mass of 10.01 amu and 80.1 percent have a mass of 11.01 amu?
Given : Atomic mass of B = 10.01 amu , % = 19.9 let it be A Atomic mass of B = 11.01 amu , % = 80.1 Solution : A and B are approximately in the ratio 1:4. Isotopic mass = [(proportion of A X at. mass of A) + (proportion of B X at. mass of B)] / 4 = [(1 X 10.01) + (4 X 11.01)] / 4 = (10.01 + 44.04) / 4 = 54.05 / 4 Isotopic atomic mass = 13.512 amu ---- Therefore, isotopic atomic mass of B is = 13.512 amu.
