To calculate the maximum amount of air in a breathing apparatus cylinder with a pressure of 204 bars and a water volume of 8 liters, the correct approach involves understanding gas laws rather than simply multiplying pressure by volume. The initial calculation of 204 bar x 8 liters is incorrect, as it mixes units improperly. The discussion emphasizes the need to clarify the units used to measure gases, which typically involve moles or volume at standard conditions. Participants highlight the importance of following forum rules that discourage direct solutions but encourage guidance to help solve the problem. Understanding the relationship between pressure, volume, and gas laws is crucial for accurate calculations.
