Lesson outcome
I can calculate the mass and the volume of a gas reactant/product given a balanced equation.
Show transcript
Equal amounts in moles of gases occupy the same volume under the same conditions of temperature and pressure.
The volume of one mole of any gas at room temperature and pressure (20℃ and 1 atmosphere pressure) is 24 dm³.
The volumes of gaseous reactants and products can be calculated from the balanced equation for the reaction.
If moles of gas are known, its density can be calculated using molar gas volume and the relationship mass = RFM x moles.
