Equal masses of H2,O2 and methane have been taken in a container of volume V at temperature 27°C in identical conditions. The ratio of the volumes of gases H2 : O2 : methane would be:

1) 8 : 16 : 1

2) 16 : 8 : 1

3) 16 : 1 : 2

4) 8 : 1 : 2  

1. Methane (CH₄) behaves as an ideal gas under standard temperature and pressure conditions. What volume is occupied by 1 kg of methane at a temperature of 35 °C and a pressure of 0.9 atm?

1.A 1-Lflask is filled with 1.30gof argon at 25 ?C. A sample of ethane vaporis added to the same flask until the total pressure is1.25atm.

Methane effused through an orifice at a rate of . Under identical conditions, how many moles of ethane gas would effuse at ?
