What is Stoichiometry?
• Stoichiometry is a chemistry equation
used to balance or convert two different
types of units
– Particles
– Grams
– Moles
– Liters
How to use it
• If 5.50cmol calcium carbide (CaC2) reacts
with an excess of water, how many moles
of acetylene (C2H2) will be produces?
CaC2+2H2OCa(OH)2+C2H2
given= 5.50 mol CaC2
given
5.50 mol CaC2
• How many moles of C2H2 produced?
5.50 mol CaC2
1 mol C2H2
1 mol CaC2
And the Answer is?
5.50 mol CaC2
1 mol C2H2
5.50 mol C2H2
1 mol CaC2
1 mol C2H2
7.50 mol C2H2
YAY!!!!
The answer is 5.50 mol
C2H2!!!
Grams to Mole
• How many moles of Ga(NO3)3 are
produced from 300 grams of silver nitrate
(Ag(NO3))?
250.0 g Ga(NO3)3
1 mole Ag(NO3)
255.733 g Ga(NO3)3
• Whats next?
Given
What we want
250.0 g Ga(NO3)3
X 1 mole Ag(NO3)
/
255.733 g Ga(NO3)3
1 mol
Ag(NO3)
0.978 mol
Ag(NO3)
