### $hortix 1. The problem statement, all variables and given/known data A breathing apparatus cylinder has a pressure of 204 bars and a water volume of 8 litres. Calculate the maximum amount of air in this cylinder at this pressure? 2. Relevant equations 3. The attempt at a solution 204 bar x 8 litres = 1632 litres? 2. Jan 29, 2014 ### voko That formula makes no sense. The left hand side is in bar x litres, the right hand side is in just litres. Besides, in what units do we really measure "amount" of gases (or any other substance)? 3. Jan 29, 2014 ###$hortix
