Chemistry Moles Packet The MOLE mol Unit that measures the amount number of particles of a substance 1 mol 6 02 x 1023 particles things 1 mol gram formula mass Why we use it atoms are sooooooo tiny that we have LOTS of them in a given sample
The mole is the basis of quantitative chemistry It provides chemists with a way to convert easily between the mass of a substance and the number of individual atoms molecules or formula units of that substance Conversely it enables chemists to calculate the mass of a substance needed to obtain a desired number of atoms molecules or Moles Packet INTRODUCTION TO MOLES We are about to start on a unit of chemical calculations called stoichiometry Stoichiometry is how we calculate the relationships between the amounts of reactants and the amounts of products

Semester 2 This semester begins with the introduction of the mole This important concept will be used during the remainder of the year as the basis for many calculations involving chemical reactions solutions and gases In the units on thermochemistry and chemical kinetics you will learn how energy is absorbed and given off during chemical Just as a dozen implies 12 things a mole abbreviated as mol represents 6 022 1023 things The number 6 022 10 23 called Avogadro s number after the 19th century chemist Amedeo Avogadro is the number we use in chemistry to represent macroscopic amounts of atoms and molecules Thus if we have 6 022 10 23 Na atoms we say we have
