Practice Problem: Molar Mass of a Gas

The video tutorial explains how to calculate the molar mass of a gas using the ideal gas law. It starts with a sample problem involving a hydrocarbon gas, providing given values such as mass, volume, temperature, and pressure. The tutorial then demonstrates how to use the ideal gas law (PV = nRT) to find the number of moles and subsequently calculate the molar mass. Finally, it identifies the gas as methane based on its molar mass and chemical composition.
