A20.0 ml sample of a nacl solution has a mass of 21.040 g. after the solution is evaporated to dryness, the dry salt residue has a mass of 4.348 g. calculate the following concentrations for the nacl solution.
a) mass/mass%
b) mass/volume%
c) molarity (m)

c.

explanation:

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).
