A mole is simply a count of something totalling 6.02 x 10^23, be it atoms, molecules, eclairs, or elephants. Conceivably, you could purchase a mole of eggs, instead of the usual dozen, if your store had a large enough warehouse. The molar mass of anything is the mass of one mole of that thing. If a single egg has a mass of 50 grams, then a dozen would have a mass of (50 grams * 12) or 600 grams. In your example, if your 1 molecule of something has a mass of 9.5 x 10 ^-22 grams, then a mole of your molecules would have a molar mass of
(6.02 x 10^23) * (9.5 x 10^-22) = 57.19 x 10^1 or 571.9 grams,
or about the weight of a dozen eggs.
