What is the atomic mass of Sulfur given the following information regarding its naturally occurring isotopes: Sulfur-32 (94.93%, 31.972 amu) Sulfur-33 (0.76%, 32.971 amu)
Average atomic mass is a measurement of the weighted-average mass of the atoms that make up an element. Typically, average atomic mass is seen on periodic tables as a number with decimal places ...
How to Calculate Average Atomic Mass: Example 1. Calculate the average atomic mass of boron given that 19.8% of its naturally occurring atoms have a mass of 10.013 amu and 80.2% have a mass of 11. ...
The point is that the isotopic variation in samples taken from all over the earth limits the precision of the atomic mass for any element, not the mass of the isotopes which are know with much greater precision. The same Wikipedia page linked earlier gives the atomic mass of europium as 151.964(1) which is inconsistent with the given percentages.

The ratio of the average mass of the atom to the unified atomic mass unit. The relative atomic mass (average atomic mass as you put it) is the weighted average mass of all the isotopes of an element in a given sample, relative to the unified atomic mass unit, which is defined as one twelfth of the mass of a carbon-12 atom in its ground state.
Steps for Finding the Average Atomic Mass of an Element. Step 1: Determine the isotopes of the element given and the percent abundance to calculate the average atomic mass. Step 2: Use the average ...
In my chem class the other day, we were working through a question about average atomic mass. We were given the following information about two isotopes of boron: Boron-10: Atomic Mass = 10.013, % in nature: 19.8%. Boron-11: Atomic Mass = 11.009, % in nature: 80.2%
The average atomic mass of europium is 151.96 amu. Calculate the relative abundance of the two isotopes. Titanium has 3 common isotopes: Ti-46, Ti-47, and Ti-50. If Ti-50 has an abundance of 45.3% and the average atomic mass of titanium is 47.90 amu, calculate the relative abundances of Ti-46 and Ti-47. Antimony has two naturally occurring ...
The average atomic mass of a sample of an element 'X' is 16.2u. What are the percentages of isotopes $\ce{^16_8X}$(atomic number = 8, atomic mass = 16) and $\ce{^18_8X}$(atomic number = 8, atomic...
