In a hospital an oxygen cylinder holds 10 L of oxygen at 200 atm pressure. If a patient breathes in 0.50 ml of oxygen at 1 atm with each breath,

Apply Boyle’s Law P1 V 1= P 2 V 2   200 x 10 = 1 x V 2   V2 =2000 L   No. of breaths = Total volume/ vol. consumed per breath   =2000/0.5x10 -3 L  =4x106
