What is the Molar mass of Fe2(SO4)3

399.88

Explanation:

The molar mass is just the number of total mass of each atom of each element.

2 - Fe = (55.845 x 2) = 111.69

3 - S = (32.06 x 3) = 96.18

12 - O = (15.999 x 12) = 191.988

For oxygen, it's being added 12 times because there is 4 in the compound times the 3 on the outside.

Now, add all of them and you have your answer!

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).

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
