The closed containers of the same capacity and at the same temperature are filled with 44 g of H_(2) in one and 44 g of CO_(2) in the other . If the pressure of carbon dioxide in the second container is 1 atm , then pressure of hydrogen in the first container would be :

Air entering the lungs ends up in tiny sacs called alveoli.From the alveoli, the oxygen diffuses into the blood. The average radius of the alveoli is 0.0050 cm and the air inside contains 14 per cent oxygen. Assuming that the pressure in the alveoli is 1.0 atm and the temperature is 37^(@)C , calculate the number of oxygen molecules in one of the alveoli.
