Chemistry Module #12 Quiz
Ideal Gas Law formula
PV=nRT
Partial Pressure formula
Pt = P1 + P2 + P3
What is the value for "R" in the ideal gas law formula? Know both the numerical value and the units that go with it.
R = (0.0821) (L) (atm)/(mole) (K)
What is the relationship between atm and torr?
760.0 torr = 1.00 atm
Combined Gas Law formula
Formula: PV/T = constant or mathematically: P1V1/T1=P2V2/T2
Boyle's Law formula and explanation
Formula: PV=constant or mathematically: P1V1 = P2V2. Explanation: At constant temperature, the pressure and volume of a gas are inversely proportional.
Charles's Law both the formula and be able to explain it
Formula: V/T= constant or mathematically: V1/T1=V2/T2 Explanation: At constant pressure the temperature and volume of a gas are linearly proportional.
What temperature scale must be used when using gas formulas?
273.15 Kelvin (or 273.15 K)
What is Dalton's Law of Partial Pressure formula?
When two or more ideal gases are mixed together, the toal pressure of the mixture is equal to the sum of the pressure of each individual gas. Pt = P1 +P2 + P3
Mole Fraction formula
X = # of moles of component/total # of moles in the mixture
What unit of pressure do you need to use when working with the Ideal Gas Law formula?
liters (L) and atmospheres (atms)
