State the Ideal Gas Equation and give the units for each of the separate values.
- PV = nRT
- P = Pressure = Pascals (Pa)
- V = Volume = m3
- T = Temperature = Kelvin (K)
- n = moles (mol)
- R = 8.31
What is the value of R in the ideal gas equation?
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 C12 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 C12 in 12 grammes of that isotope (Avogadro's Number of Particles according to the definition sheet)
