How many total atoms are in 1 mole of H2O?

1.806 x 10^24 atoms total

Explanation:

There are 2 moles of hydrogen atoms in a mole of water molecules and 1 mole of oxygen atoms. Two hydrogen atoms and one oxygen atom form a water molecule.

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).
