Moles/Molar Mass

A quantity the chemists use to measure amounts of elements and compounds

One mole = 6.02 x 10^23 molecules/atoms/ions

N = one mole = 6.02 x 10^23 molecules/atoms/ions

NaCl = one mole = 6.02 x 10^23 molecules/atoms/ions

The coefficients of a balanced equation represents the molar ratio of reactants and products in the reaction. NOT THE SUBSCRIPTS (TINY NUMBERS ON BOTTOM RIGHT)

6.02 x 10^23

The mass in grams of one mole of a substance

Atomic mass on periodic table

• Ex. Sulfur = 32.07 x 8 = 256.56 g/mol
• SULFUR EXISTS AS 8 ON ITS OWN
• IF SULFUR IS IN A COMPOUND, MULTIPLY THE
• MOLAR MASS BY ITS SUBSCRIPT
