Chlorine has two isotopes, 35cl and 37cl; 75.77% of chlorine is 35cl, and 24.23% is 37cl. the atomic mass of 35cl is 34.969 amu, and the atomic mass of 37cl is 36.966 amu. what is the atomic weight of chlorine?

The average atomic mass of chlorine is 35.45 amu

Explanation:

Mass of isotope - 35 = 34.969 amu

% abundance of isotope-35 = 75.77% =

Mass of isotope - 37 = 36.966 amu.

% abundance of isotope-37  = 24.23% =

Formula used for average atomic mass of an element :

Therefore, the average atomic mass of chlorine is 35.45 amu

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).
