Calculating Masses


 * -|Relative Atomic Mass=

Relative Atomic Mass
$${(isotope 1  mass \times Relative Abundance)+(isotope 2   mass  \times Relative Abundance) +(isotope 3   mass  \times Relative Abundance) \over 100}$$

What Is Relative Atomic Mass
The Relative Atomic Mass is the weight in grams of atoms of an element contained in 12g of carbon-12

Calculating Relative Atomic Mass
The formula is for Relative Atomic Mass is:

$${(isotope 1  mass \times Relative Abundance)+(isotope 2   mass  \times Relative Abundance) +(isotope 3   mass  \times Relative Abundance) \over 100}$$

The number of isotopes averages on the top by 100 depends on how much isotopes there are, for example:

Examples
Ag/Silver has 2 Isotopes:
 * -|% Abundance of the Lighter Isotope=

What Is % Abundance of the lighter Isotope?
the percentage of atoms with a specific atomic mass, in this case we are finding the % abundance of the Lighter Isotope
