16 Chem Ch 10 Review

review of stoichiometry

QuestionAnswer
yield of 100% product only found on paper theoretical yield
SI unit for amount of substance moles (mol)
Number of liters in 1 mole of any gas at STP 22.4
Number that tells the number of moles in a chemical equation coefficients
STP conditions 0 degrees Celsius , 1 atm
Avogardro's Number 6.02 x 10^23
Units for molar mass grams (g) or atomic mass units (u)
Formula always using the lowest whole number ratio empirical
Formula that may not be in the lowest whole number ratio molecular
yield of product from doing the lab experiment actual yield
ratio of actual / theoretical x 100 percent yield
this is conserved in every chemical reaction (equation) mass & number of atoms
Non-SI units for volume Liters (L)
STP conditions apply to this state of matter gases
P and As are this type of element tetratomic
H, N, O , F, Cl , Br, I are this type of element diatomic
S is this type of element octatomic
most elements are this type monatomic
Avogadro's number has these units representative particles
ratio of atomic mass of element / molar mass of compound x 100 percent composition
