Mole Volume Relationships

Avogadro's law states that equal ​volumes of gases at the same temperature and ​ pressure contain ​---.

• equal numbers of particles

• equal masses

• different numbers of particles

• different masses

Why do equal numbers of small and large gas particles occupy the same volume?

• large expanses of space exist between gas particles

• large particles move more slowly than smaller particles

• there are fewer collisions between smaller gas particles
