• Finally, from two obvious equations we derive both the number and the diameter of the molecules which constitute, let us say, a gram-molecule of the gas.

Jean Baptiste Perrin - Nobel Lecture

• For each simple substance the gram-molecule of a compound contains as many gram-atoms as the molecule contains atoms of this simple substance, and the gram-atom is the product of the mass of the atom and Avogadro's number N.

Jean Baptiste Perrin - Nobel Lecture

• And the gram-molecule (22,412 c.c. in the gaseous state under normal conditions) will contain 22,412 times more molecules: this number will be Avogadro's number.

Jean Baptiste Perrin - Nobel Lecture

• The number N of the molecules constituting any gram-molecule is Avogadro's number.

Jean Baptiste Perrin - Nobel Lecture

• V '= 161. 82x6001/273 = 3557 litres or at the temperature of explosion 1 gram-molecule of nitro-glycerine produces 3,557 litres of permanent gas.
