CHEM 101: Chemistry and Society

This video guides viewers through the process of calculating the volume occupied by Hydrochloric acid gas or HCl at standard temperature and pressure. Using the molar mass of HCl and its properties as an ideal gas the tutorial comprehensively explains each step to determine the volume from a given mass at STP. A must-watch for understanding gas volume conversions in chemistry

This instructional video guides you through the process of determining the number of molecules in a given sample. It illustrates the conversion from grams to moles using the molar mass of the substance and then to molecules using Avogadro's number, providing a practical example with ethane (C?H?) to calculate approximately 6.67 x 10²¹ molecules in a 0.334 g sample.
