The molar mass of calcium chloride (CaCl2) represents the mass of one mole of what?
Represents the mass of one mole of calcium chloride, which is
The molar mass is the mass of
Thus in one mole of calcium we have
Why do we use
Well it enables us to equate the macro world of grams and kilograms, what we measure on a balance, with the submicro world of atoms and molecules, of which we can conceive, but cannot observe directly. The concept of molar equivalence is central to the study of chemistry. If you know the formula, and you know the mass of the stuff, use of
