Stoichiometry: Calculations with Chemical Formulas and
... • By definition, these are the mass of 1 mol of a substance (i.e., g/mol) – The molar mass of an element is the mass number for the element that we find on the periodic table – The formula weight (in amu’s) will be the same number as the molar mass (in g/mol) Stoichiometry ...

... Analyze We are told that isopropyl alcohol contains C, H, and O atoms and given the quantities of CO 2 and H2O produced when a given quantity of the alcohol is combusted. We must use this information to determine the empirical formula for isopropyl alcohol, a task that requires us to calculate the n ...

... Balancing equation is a very, very important question. To balance a chemical equation, you must make sure the number of atoms of each kind at both sides of the arrow is identical. Also start examining the most bulky species, that is, the one with the most different kinds of atoms and number of atoms ...
