Boom

  • You can use the volume ratios as conversion factors in gas stoichiometry problems as you would mole ratios.
  • Ideal Gas Law
  • You have learned about equations describing the relationships between 2 or 3 of the 4 variables - Pressure, Volume, Temperature and number of moles - needed to describe a sample at a time.
  • All of the laws you have learned thus far can be combined into a single equation, the IDEAL GAS LAW: the mathematical relationship among pressure, volume, temperature, and number of moles of a gas.
  • R is a constant
  • PV=nRT
  • In the equation representing the Ideal gas law, R = idea gas constant
  • Its value depends on the units chosen for pressure, volume, and temperature in the rest of the equation.
  • Measured values of P, V, Temp., and n for a gas at near-ideal conditions can be used to calculate R
  • R = 0.082058
  • P.S. I left the floor open for comments containing some of the notes, I purposely left out some bullet points.

    I'm surprised nobody mentioned that one mole of an ideal gas at STP has of volume of 22.4 liters, STP being standard pressure and temperature, where standard pressure is 1 atm and standard temperature is zero degrees kelvin.

    Thanks for leaving some room for comments, Nick.

    and good catch Jim

    Standard temperature is 0 celsius, therefore 273.15 kelvin
