SUMMARY
The molecular weight (MW) of an unknown gas can be calculated using the Ideal Gas Law formula, PV = nRT. In this discussion, a sample weighing 0.0097561 g occupies 0.2 L at a temperature of 500 K and a pressure of 2 atm. The calculation yields a molecular weight of 1 g/mol, confirming the accuracy of the result. The discussion emphasizes the importance of showing work in calculations to identify potential errors.
