Page 15 - ... the molecular weight of a compound is the sum of the atomic weights of its elements.
Page 4 - Avogadro, which asserts that equal volumes of different gases under like conditions of temperature and pressure contain the same number of molecules.
Page 16 - To find therefore, the percentage amount of any constituent in a molecule, we have the following rule : — Multiply the atomic weight by the number of atoms and this product by 100. Divide the final product by the molecular weight, and the quotient will be the percentage amount of that constituent.
