Sorry if it's wrong.
The <span>process
melts an ore to separate useful metals from the rest of the elements in the ore
is called smelting. The ore is heated beyond its melting point to extract the
metal with the help of oxidizing agents such as air or reducing agents such as
coke. </span>
Answer: mass and relative abundance of each isotope of that element
Explanation:-
For example:
If an element X has two isotopes with following masses ad abundance:
Mass of isotope 1 = 267.8 amu
% abundance of isotope 1 = 87.8% = 0.878
Mass of isotope 2 = 269.9 amu
% abundance of isotope 2 = 12.2% = 0.122
Formula used for average atomic mass of an element :

![\text{ Average atomic mass of an element X}=\sum[(267.8\times 0.878)+(269.9\times 0.122)]](https://tex.z-dn.net/?f=%5Ctext%7B%20Average%20atomic%20mass%20of%20an%20element%20X%7D%3D%5Csum%5B%28267.8%5Ctimes%200.878%29%2B%28269.9%5Ctimes%200.122%29%5D)
