Other Stoichiometry Variations - Gas Volumes, Density, Molarity

For a moment, consider the volume of air in two huge rooms. Room A is empty. Room B is the same size as Room A, except there are ten small helium-balloons that are at the top of the ceiling. When measuring the volumes of the rooms, making sure to subtract the volume of the balloons in Room B, is the volume different? View this presentation to learn how the volumes of the two rooms compare, as well as more about Avogadro's Principle, density, and molarity.
