Questions and Answers 100% Pass
How do you convert to Kelvin from degrees Celsius? - ✔✔K= C + 273.15
The LITER is also interchangeable with what unit? - ✔✔dm^3
What is an EXTENSIVE PROPERTY? - ✔✔a property that is proportional to the amount
What is an INTENSIVE PROPERTY? - ✔✔a property that is independent of the amount
What are DERIVED INTENSIVE PROPERTIES? - ✔✔molar quantities
Define ATOMIC MASS UNIT (AMU) - ✔✔1 amu = 1/12 mass of 1 atom of 12C
= 1.6605 X 10^-24 g
= mass of proton = mass of neutron (approx.)
Define ATOMIC WEIGHT (AW) (aka Atomic Mass) - ✔✔mass of an atom, in amu

How do you convert from moles to molecules? - ✔✔n = N/NA
How do you convert from molecules to atoms? - ✔✔Use the formula
What do n, m, M, N, and NA stand for? - ✔✔n= number of moles
m= mass
M= molar mass
N= number of molecules
NA= 6.022 X 10^23 (Avogadro's number)
Boyle's Law states... - ✔✔from measurements performed at constant temperature and
number of moles, the volume of a gas is INVERSELY proportional to the applied
pressure
Charles' Law states... - ✔✔from measurements performed at constant pressure and
number of moles, the volume of a gas is DIRECTLY proportional to the absolute
temperature
