Under identical conditions of pressure and temperature

1.	Under identical conditions of pressure and temperature
Answer» `(r_(H_2))/(r_(O_2)) = 4` `(r_(H_2))/(r_(CH_4)) = 2.83` `(r_(He))/(r_(CH_4)) = 2` `(r_(He))/(r_(SO_2)) = 4` SOLUTION :`(gamma_(H_2))/(gamma_(O_2)) = SQRT((32)/(2)) = 4 , (gamma_(H_2))/(gamma_(CH_4)) = sqrt(16/2) = sqrt(8) = 2.83`. `(gamma_(He))/(gamma_(CH_4)) = sqrt((16)/(4)) = 2 , (gamma_(He))/(gamma_(SO_2)) = sqrt((64)/4) = 4`.
