One mole of any _______________ contains _________________ molecules. Learning Target: I CAN Develop a relationship between mass and volume and apply the Ideal Gas Law to gas problems

January 2, 2017 Ideal gas law We have ideal conditions or assumptions regarding gases using the Kinetic Molecular Theory (KMT). We also have an Ideal Gas Law to calculate multiple pieces of information at the same time. PV = nRT Learning Target: I CAN Develop a relationship between mass and volume and apply the Ideal Gas Law to gas problems

Ideal gas law PV = nRT P = pressure (atm) n = moles of gas (moles) January 2, 2017 Ideal gas law PV = nRT P = pressure (atm) n = moles of gas (moles) V = volume (L) T = temperature (K) R = 0.082 (l*atm)/(k*mol) Learning Target: I CAN Develop a relationship between mass and volume and apply the Ideal Gas Law to gas problems
