• if vapour pressure of any gas is 20 with respect to ethane gas calculate its molecular weight
• 22.4 l of water vapour at ntp when condensed to water occupies an approximate volume of
• 1.0 mole of nitrogen and 3.0 moles of PCl 5 are placed in 100 L vessel heated to 227 o C. The equilibrium pressure is 2.05 atm. Assuming ideal behaviour, calculate the degree of dissociation for PCl 5 and K p for the reaction, PCl 5 (g)?PCl 3 (g)+Cl 2 (g).
• The volume of SO2 gas (in l.mol 1) at 0?C and 1 atmospheric pressure-760mm of Hg is equal to 22.4. Estimate the value of volume of the gas at 20?C and 1 atmospheric pressure. Use Avogadro’s law of gas.
• an ideal gas mixture contains 4 milimoles of H2 for every mili mole of Ne .The partial pressure of Ne is ?
  
• 696v7v
  
• What is a pressure in stp ? What we choose in sum1 atm or 1 bar at stp ?  
• Is pressure directly proportional to temperature and inversly proportional to volume 
• You are provided with samples of O2,N2,CO2 and CO under similar conditions of temperature and pressure that they contain the same number of molecules represented by letter M . The molecules of O2 occupy the volume of N litres and have a mass of 8g under similar conditions of temperature and pressure A) I) what volume is occupied by M molecules of N2? II) what volume is occupied by 3M molecules of CO ? B) what is the mass of CO2 in grams C) name the law of above questions
• The volume occupied by a certain gas was found 5.6 dm3  when the pressure was 2 atmosphere. If the  pressure is increased by 15%, find the new volume of the gas.
