State the Ideal Gas Equation and give the units for each of the separate values.
PV = nRT
P = Pressure = Pascals (Pa)
V = Volume = m^{3}
T = Temperature = Kelvin (K)^{ }
n = moles (mol)^{ }
R = 8.31^{ }
What is the value of R in the ideal gas equation?
8.31
What is the definition of the term "Relative Atomic Mass" ?
The ratio of the average mass of an element relative to 1/12th the mass of a Carbon-12 atom.
Define Avogadro's constant.
The number of C^{12} atoms in exactly 12 grams of Carbon-12 (the number of particles in 1 mole of a substance)
What is the definition of a mole?
The amount of a substance which contains the same number of "entities" as there are of C^{12 }in 12 grammes of that isotope (Avogadro's Number of Particles according to the definition sheet)
Give definitions for both Empirical Formula and Molecular Formula
