...at a much less cost than that of gas. Mr Bowditch has been very successful in arranging carbonators for this purpose, and his experiments have proved...conclusion was drawn from the desire to reconcile and equalize the combining volume of all elements with their combining weights or atomic weights. The working...

...sulphur. It is necessary to postulate the inviolable nature of Avogadro's law that equal volumes of gases, under similar conditions of temperature and pressure, contain the same number of molecules, and the above apparently capricious data become clear. To take an example from each class...

...Molecules. — According to the law of Avagadro — "Equal volumes of all bodies in the gaseous state, under similar conditions of temperature and pressure, contain the same number of molecules" — it follows: (1) That the molecules of all bodies in the gaseous state must be of the...

...is referred to as the law of pressures. (4) Avogadro's law. It states the equal volumes of all gases under similar conditions of temperature and pressure contain the same number of molecules. Let us consider equal volumes V of two different gases at the same temperature and pressure....
