The name for the number used to convert between moles and atoms, molecules, or particles.
Avogadro's Number
This term refers to the tag given to a number to identify what it is measuring
Units
This term refers to the fraction used in stoichiometry.
This is the number that refers to how many steps a gram to gram stoichiometry problem typically contains.
3
This scientist proposed the idea of atomos.
Democritus
This numerical value is found beneath the elemental symbol, and is used to convert between moles and grams.
molar mass
How many atoms are there in 2.0 moles of sodium?
1.20 x 1024 atoms of sodium
This term refers to the location where the given's coefficient is placed within the mole fraction.
denominator (bottom)
This value is used in gram to gram stoichiometry problems to convert between grams and moles.
molar mass
This scientist conducted the experiment that led to the discovery of the nucleus of an atom.
Rutherford
This unit is used to measure mass
grams
Convert 4.5 x 1024 molecules of NaCl to moles of NaCl
7.47 moles of NaCl
numerator (top)
This refers to what is used in the middle step of a gram to gram reaction. (found from the balanced reaction)
mole fraction (ratio)
This reaction type requires the presence of oxygen and produces carbon dioxide and water.
Combustion
This term refers to the way we view the mole, similar to a dozen or a pair.
Counting Unit
Convert 450 grams of lithium to atoms of lithium.
3.90 x 1025 atoms of lithium
K + Cl2 → KCl
If 2.0 moles of Cl2 react, how many moles of KCl are produced?
4.0 moles KCl
2Na + Cl2 → 2NaCl
If 3.5 grams of sodium react, how many grams of NaCl are produced?
8.90 g of NaCl
This reaction type can be thought of as the process of breaking apart.
Decomposition
This numerical value serves as the exponent in Avogadro's Number
23
This value was given in classwork practice to convert between moles and volume (liters).
1 mole=22.4 L
H2 + O2 → H2O
If 1.0 moles of O2 react, how many moles of H2 must have reacted completely ?
4 moles of H2
CH4 + O2 → CO2 + H2O
