## How do u find the mass of an atom?

In an element atomic mass of an atom can be calculated by adding the mass of protons and neutrons.

## How do you calculate average mass?

To calculate the average atomic mass, multiply the fraction by the mass number for each isotope, then add them together. Whenever we do mass calculations involving elements or compounds (combinations of elements), we always use average atomic masses.

## What is the weighted average mass of silicon?

## How do you find the mass of an atom?

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

## What is the mass of one atom of an element?

Mass of one atom of an element is 2.66 × 10^-23g .

## What is the average atomic mass of an element?

The average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12.

## How do I calculate the average?

Average This is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.
