Q4. C Motion of gases is random regardless of mass and they take up whatever space is available Q15.D (You skipped somehow) C2H5 : CO2 = 1:5 So moles of CO2 = 5*0.1 = 0.5 mol Volume of CO2 = 0.5*24(Molar gas volume) =12 Q31. B Question asks for Lowest percentage not highest

31. Answer is B. Question asks for LEAST percentage by mass

According to the mark scheme, the answer to Q4 is actually C. I had the same thought process you did, so could you please correct why B is wrong? 7:25

Hey! So basically according to the kinetic particle theory all gas molecules have a random constant motion. Thus, they are spread out randomly in a given space regardless of their densities.... The density will only affect the rate of diffusion... Hopefully, that makes it clear.
