The video tutorial covers Avogadro's contributions to chemistry, focusing on his principle that equal volumes of gases at the same temperature and pressure contain equal numbers of particles. It explains the concept of molar volume, particularly at standard temperature and pressure (STP), and demonstrates how to calculate the volume of a gas at STP using ethylene as an example.
