Section 3.3- The Mole Flashcards
the sum of the atomic masses of all the atoms in the formula of the compound
molecular mass
to relate microscopic values like atomic masses to the macroscopic values measured in the laboratory, chemists use _______________________
the number of atoms in exactly 12g of carbon-12
Avogadro’s number
Avogadro’s number is
6.022 x10^23
the link between the microscopic and macroscopic levels of chemistry
Avogadro’s number
a term that is nearly synonymous with Avogadro’s number is __________________
Avogadro’s number of anything
mole
the amount of a substance containing the same number of particles as exactly as 12 g of carbon-12
mole
the _______________________ of a substance is the mass per mole of the substance
molar mass
the molar mass of any substance in grams per mole is numerically equal to the
atomic or molecular mass of that substance in atomic mass units
1 mole =
6.022x10^23
or
molecular mass in grams
the link between mass and number of particles
