The Mole
This is the NAME of the number used to relate moles to small things.
What is avogadro's number?
What value do we used to convert between moles and small "things?"
What is 6.02 x 1023?
What baking term did we use to describe how stoichiometry works?
What are recipes?
2NO(g) + O2(g) → 2NO2(g)
If 40 moles of O2 react, how many grams of NO2 are formed?
What is 2400 grams of NO2
Why is Avagadro's number so large?
What is because atoms are very small.
What value do we use to convert between moles and mass (grams?)
What is molar mass?
What must be done before completing a stoichiometry calculation?
What is balancing a reaction?
2NO(g) + O2(g) → 2NO2(g)
If 56 grams of NO2 are produced, how many grams of O2 were consumed?
What is 19.5 grams O2?
What is molar mass?
What is the mass of one mole of something?
How many atoms are there in 2.0 moles of Cu?
1.20 x 1024 atoms of Cu
What do we call the ratio that we used to do mole-mole stoichiometry calculations?
What is the mole ratio?
2NO(g) + O2(g) → 2NO2(g)

What is 2.02 g/mol?
How many grams are there in 3.5 moles of NaCl?
204.54 g NaCl
