2. how many pencils are in a dozen pencils?
3. write two forms of the conversion factor that will convert a dozen to number of
objects and number of objects to dozen.
4. using the appropriate conversion factor in #2, convert 3.75 dozen eggs to number of
eggs.
5. using the appropriate conversion factor in #2, convert 248 eggs into dozens of eggs.
6. similarly, the mole (mol) is a unit for counting objects. it is especially useful for
counting tiny objects like atoms, molecules, ions, and formula-units.

sry but any answer choices

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).

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
