Find the relative rate of diffusion for the gases chlorine, cl2 and ethane, c2h6

The ratio of the rates is equivalent to the square root of the ratio of the molar masses.
Molar mass of chlorine: 71
Molar mass of ethane: 30

V(Cl) / V(C₂H₆) = √(30 / 71)
V(Cl) / V(C₂H₆) = 0.65

The relative rate of diffusion of chlorine to ethane is 0.65

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
