how do you calculate the Average Atomic Mass Calculator-

**In finding the atomic mass**, follow these steps

- Start with the formula:
**A = Z + N.** - Replace Zand N with the real values for the numbers of protons and neutrons respectively.
- Add the sum to get the atomic mass A as your answer.

In reality, the mass number of an element is determined by the number of protons plus neutrons : **mass number = protons + neutrons**.

We use this formula to find the relative atomic mass is **∑ isotope mass x isotope abundance / 100**. Relative molecular mass (Mr) is the weighted average of the mass of a molecule compared to 1/12 of the mass of the carbon-12 atom. Mostly used when discussing about covalent compounds.
