The Mole Flashcards
average atomic mass
the average of the masses of all the Isotopes of an element
given in atomic mass units (u)
isotopic abundance
the relative amount of an isotope of an element
percent or decimal
the mole
contains the same number of particles as exactly 12g or carbon-12
molecular mass
the mass of 1 molecule of a substance
given in atomic mass units (u)
molar mass
the mass of 1 mol of a substance. numerically equal to the elements average atomic mass
(g/mol)
empirical formula
the lowest whole number ratio of Atoms of each element in a compound
molecular formula
the actual number of Atoms of each element in a molecule or formula unit
theoretical yield
the calculated amount of product that is produced by a chemical reaction
actual yield
the measured quantity of product obtained in a chemical reaction
list 4 things that can reduce actual yield
reaction does not go to completion
impurities in reactants
side reactions
experimental error
