A cell in your adrenal gland has about 2.5 * 10^4 tiny compartments called vesicles that contain the hormone epinephrine (also called adrenaline). (a) An entire cell has about 150 fmol of epinephrine. How many attomoles (amol) of epinephrine are in each vesicle? (b) How many molecules of epinephrine are in each vesicle?
(c) The volume of a sphere of radius r is r/3 πr^3. Find the volume of a spherical vesicle of radius 200 nm. Express your answer in cubic meters (m3 ) and liters, remembering that 1 L = 10^-3 m^3.
(d) Find the molar concentration of epinephrine in the vesicle if it contains 10 amol of epinephrine.

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).
