Full Answer

According to the Encyclopaedia Britannica, Avogadro’s number is the number of units, usually atoms or molecules, found in one mole of any substance. This means that a mole, by definition, always contains the same number of units, regardless of the substance.

A mole is related to atomic weight or mass. For example, one mole of carbon-12 atoms has an atomic weight of 12 grams, while a mole of oxygen, which would also contain an Avogadro's number of units, has an atomic weight of 16 grams. This shows that oxygen has a greater mass than carbon.

    Who invented exponents?

    A:

    Euclid discovered the concept underlying the exponent, calling the area of a square a power of the length of a single side. Archimedes later generalized the idea of powers in his work, "The Sand Reckoner." He discovered and proved the law of exponents in the same work.
