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 else can I help you with?
What element has the isotopic mass of 209?
The element with the isotopic mass of 209 is Bismuth (Bi).
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.
Is the isotopic mass of given isotope ever an exact while number?
No, the isotopic mass of an isotope is not an exact whole number because it accounts for the average mass of all the isotopes of that element found in nature, which have different masses due to varying numbers of neutrons. The isotopic mass is usually reported as a decimal number.
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.
What is needed to find the average atomic mass of the element?
To find the average atomic mass of an element, you need to know the isotopic masses of each of its isotopes and their relative abundances. Multiply the isotopic mass of each isotope by its relative abundance, then sum these values to calculate the average atomic mass.
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?
To calculate the mass of phosphorus in 45.3 g of ammonium phosphate, you need to know the molar mass of ammonium phosphate (NH4)3PO4, which is approximately 149.09 g/mol. The mass percentage of phosphorus in ammonium phosphate is 30.97%. Therefore, the mass of phosphorus in 45.3 g of ammonium phosphate can be calculated as: 45.3 g x (30.97/100) = 14.02 g of phosphorus.
How do you find relative isotopic mass?
its the same as the mass number e.g. oxygen(-16) is 16, carbon-12 is 12 but carbon-13 is 13 because it has an extra neutron i think anyway Really? I thought that the relative istopic mass was a ratio of the average atomic mass of the element compared to the average atomic mass of carbon. For example chlorine has an average atomic mass of 37 and carbons atomic mass is 12 so its 37 divided by 12 which is about 3:1.
What is the mass percentage of ammonium hydrogen phosphate?
The chemical formula is (NH4)HPO4 (if you think to this phosphate). The molar mass is 132,07. The percentages of the elements are: - hydrogen: 6,86997 % - nitrogen: 21,21196 % - oxygen: 48,45843 % - phosphorous: 23,45964 %
