Mass/volume

no detectable gain or loss of mass occurs in chemical reactions. Mass is conserved

in a given chemical compound, the elements are always combined in the same proportions by mass

whenever two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers

• mass of element
• mass of whole sample ^{x 100%}

simplest whole number ratio of atoms of each element in a compound

(actual yield/theoretical yield) x 100%

• name the metal first
• stem of nonmetal + ide ending

• name more metallic element first
• ide ending to last element
