The mole
A method of Counting materials used in chemical reactions.
reacting
Counting total number of atoms is not practical since most reactions involve large numbers of atoms…….
particles
The mole is defined as a number of…………
Avogadro’s Number
6.02 x1023 particles make up one mole which is called……………….
grams
One mole of an element is equal to the element’s atomic mass measured in……………..
63.54 grams
One mole of copper would weigh………….
26.98 grams
One mole of aluminum would weigh……………..
molar mass
The mass of one mole of any substance is called its……………..
elements
If you add the mass of all…………… in a compound, you will get the mass of one mole of the molar mass.
S = 32 neutrons
Oxygen = 16 neutrons multiplied by 3
SO3 = S + O + O + O
32 + 16 (3)
32 + 48 = 80 g/ml
Final answer: 80 g/ml
Example: What is the molar mass of Sulfur Oxide (III) which is SO3?
