1811년, 아보가드로(Avogadro)는 동일한 압력과 온도에서 모든 기체는 동일한 부피속에 동일한 수의 입자(분자)를 포함하고 있다는 가설을 발표했습니다.
He derived this from the uniformity of the behaviour of (ideal) gases on increases in temperature and pressure (see the Gas Laws) and the Law of Volumes. When Avogadro's supposition is correct, then 6 parts by volume of CO and 3 parts by volume of O2 must form 6 parts by volume of CO2 when pressure and temperature are the same before and after the reaction. Similarly, at a temperature a little above 100°C, a gas mixture containing 6 parts by volume of H2 and 3 parts by volume of 02 must give 6 parts by volume of steam, and a mixture containing 5 parts by volume of H2 and 5 parts by volume of Cl2 must give 1 0 parts by volume of HCI. In the following experiments we will carry out the reactions named above to test the correctness of the hypothesis.
