You don't specify when you're talking about, so the answer is no.
The Atomic Mass scale used to be based on the mass of hydrogen, and then it was changed to be based on the mass of oxygen.
The problem is that some scientists used specifically the isotope oxygen-16 for the mass basis, and some used natural abundance oxygen, which includes other isotopes. So atomic mass values, even very carefully measured ones, would differ somewhat from chemistry journals to physics journals.
A few decades back they decided to redefine the mass scale again, this time explicitly basing it on the isotope carbon-12, isolated, in both its electronic and nuclear ground states, so all scientists today should be using the same scale.

Does the mass of each element in a compound depend on the amount of compound?
Yes, because the mass of each element in a compound depends on the mass of the compound.
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes. The gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that isotope.
How do scientists determine the atomic mass of an atom?
By the number of protons and neurons in a element. each has a relative atomic mass of 1. an electron weighs around a 2000th of this, so is ignored for Ar calculations
Do the Empirical formula relates the mass of each element in a compound to the entire mass of the compound?
An empirical formula gives this information indirectly by specifying the ratios of numbers of atoms of each element in a compound to the total number of atoms in a compound. These ratios can then be mathematically converted into the mass ratios specified in the question by using the known atomic weights of each element present: The mass ratio of element "Q" to element "R" is equal to the number ratio multiplied by the ratio of the atomic weight of element Q to that of element R. For example, the number ratio of hydrogen to oxygen in water is 2, but the mass ratio is 2(1.008/15.999) = 0.1260.
What Is the weighted average of all of the isotopes of an element.?
The answer is the atomic weight of the original element: It's the number on the top left of each element square of the Periodic Table.
What do you call the mass of an element?
The mass of an element is known as it's ATOMIC Mass.
What is the percent compistion of a compound?
The percent composition of a compound tells the amount of each element in the compound as a percentage. It is possible to find if the mass of an element and the total mass of the compound is known.
If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
Does the mass of each element in a compound depend on the amount of compound?
Yes, because the mass of each element in a compound depends on the mass of the compound.
If an element had three isotopes with known masses what other information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
Why need to know the percentage of each isotope of an element to determine the atomic mass?
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
Scientists have found that properties of an element are more closely related to their?
atomic mass
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes. The gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that isotope.

The average mass of all the known isotopes of an element is what?
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
