2 gm of O_(2) at 27^(@)C and 760 mm of Hg pressure has volume "____________" .

Calculate root mean square speed most probable speed and average speed of (a) SO_(2) at STP (b) Ethane at 27^(@)C and 760 mm of hg (c ) O_(2) if its density is 0.0081 g mL^(-1) at 1 atm (d) O_(2) if 6.431g of it occupies 5 litre at 750 mm (e) O_(3) at 92 cm 20^(@)C .

A 1 L flask contains 32 g O_(2) gas at 27^(@)C . What mass of O_(2) must be released to reduce the pressure in the flask to 12.315 atm?

The air contain 80% N_(2) and 20% O_(2) by volume. The volume occupied by 40 gm air at 27^(@)C and 760 mm Hg pressure approximately. [Given: R=0.08atm-litre- "mol"^(-1)K^(-1) ]

If 1 litre of N2 at 27^(@)C and 760 mm Hg contains N molecules, 4 litres of O_(2) under the same conditions of temperature and pressure, shall contain

A simple of thliqid H_(2)O at 18.0 g is inlected into an evacuated 7.6 L flask maintained at 27.0^(@)C . If vapour pressure of H_(0)O at 27.0^(@)C is 24.63 mm Hg, what wight percentage of the water will be vaproueied when the ssystem comes to equilibrium? Assume water vapours behaves as an ideal gas. The volume occupied by the liquid water is negligible compared to the volume of the container:
