Mole is the term used to express the quantities of substances involved in a chemical reaction. Mole is defined as the amount of a substance that contains Avogadro's number of particles
(atoms, ions, molecules, etc.). Avogadro's number is defined as the number of atoms present in 12 g of carbon-12 isotope, with a numerical value equal to 6.022 x 1023. The mole is a
unit similar to a dozen; one dozen
equivalent to 12 the same way that one mole is equivalent to 6.022 x 1023.
You could use this information to write equalities:
12 molecules of H2O = 1 dozen of H2O
6.022 x 1023 molecules of H2O = 1 mol of H2O
For example, if I had 18 molecules of water, I would have
18 molecules of water x
dozen of water
= 1.5 dozen of water
12 molecules of water
Molar mass is the mass in grams of 1 mol of substance numerically equal to molecular weight in amu (atomic mass unit). Mass is a measure of quantity, and when you use a balance to
weigh a sample, the scale is using a set of standards to determine…
Valuable minerals (chemicals) can be obtained from ores, which are natually occuring mixtures. One ore cotains 38% magnetite, a mineral with the chemical formual Fe3O4. Fe3O4 contains 72.4% iron. What mass of ore (in tons) would contain 3.5 tons of iron? (Hint: your mass percent conversion factors can have units of tons)
*Mass percent values used in calculations should be written as conversion factors with units & labels
