Use PT for conversions involving mass Unless you want to memorize the masses of all the elements!! Molar Mass of Compounds ? = to sum of masses of atoms in compound's formula ? Round atomic masses to whole number Ex: H2O ? 2 H’s = 2 x 1g = 2g ? 1 O = 1 x 16g = 16g ?

The material can be apure substance, which contains only one chemical component; in this case, the chemical composition corresponds to the relative amounts of the elements constituting the substance. Normally, it can be expressed with achemical formula. For an example, the chemical formula for wat...
