The atomic mass of silver is 107.8

Explanation:

Average atomic mass is the average mass of all the isotopes present depending on the relative abundance of each isotope.

Mass of isotope A = 106.9051

% abundance of isotope 1 = 51.82% =

Mass of isotope B = 108.9047

% abundance of isotope 2 = (100-51.82)% =

Formula used for average atomic mass of an element :

Therefore, the average atomic mass of silver is 107.8

its first and third is your answer i did the qustion the fourth isnt right

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
