The air tanks used by a certain fire department each contain 25.0 l of air at a pressure of 200.0atm and a temperature of 293 k. Assume the average fire fighter exhales 0.500l of air per breath at a temperature of 310.0 k, exhales 30.0 times per mintues that the exhaled air is at a preassure of 1.00 ATM and the air behaved as an ideal gas. Calculate the time in hours before a fire fighter using such an air tank runs out of air.
