How do you calculate the average atomic mass of sulfur?

In your case, the average atomic mass of sulfur will be calculated using the given atomic masses of its four isotopes and their respective decimal abundance, which is simply the percent abundance divided by 100 .

How is average atomic mass calculated?

The average atomic mass for an element is calculated by summing the masses of the element’s isotopes, each multiplied by its natural abundance on Earth. When doing any mass calculations involving elements or compounds, always use average atomic mass, which can be found on the periodic table.

How can I calculate average?

Average equals the sum of a set of numbers divided by the count which is the number of the values being added. For example, say you want the average of 13, 54, 88, 27 and 104. Find the sum of the numbers: 13 + 54 + 88+ 27 + 104 = 286. There are five numbers in our data set, so divide 286 by 5 to get 57.2.

What is the formula mass?

The formula mass of a substance is the sum of the average atomic masses of each atom represented in the chemical formula and is expressed in atomic mass units. The formula mass of a covalent compound is also called the molecular mass.

What is the atomic mass of Sulphur?

What is the abundance of Si-28?

92.23%
The abundance of Si-28 is 92.23%. Si-29 is 4.68% and Si-30 is 3.09%. Because most Si atoms have a mass of 28 amu, the average mass of all silicon atoms is very close to 28.

What is the amu of SI-29?

28.9765
A sample of naturally occurring silicon consists Si-28 (amu = 27.9769), Si-29 (amu = 28.9765) and Si-30 (amu = 29.9738). If the atomic weight of silicon is 28.0855 and the natural abundance of Si-29 is 4.67%, what are the natural abundances of Si-28 and Si-30?

What is sulfur formula?

Sulfur (in British English: sulphur) is a chemical element with the symbol S and atomic number 16. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature.
