Hey!!
here is your answer >>>
let us multiply the two numbers above!. we get,
(7.51)(6.50) ( 10) / 1.62 (10 )^-6
(7.51)(6.5)(10)^7/1.62
(751)(650)(10^3) / 1.62
301327.160 (10^3)
301327160 is the number.
Hope my answer helps!
The ratio of the diffusion rate of Cl2 and O2 is 1.5
calculation
rate of diffusion Cl2/ rate of diffusion O2 =√ molar mass of Cl2/ molar mass of O2
molar mass of Cl2 = 35.5 x2 = 71 g/mol
molar mass O2 = 16 x2 =32g/mol
that is rate of diffusion Cl2/ rate of diffusion of O2 =√ 71/ 32= 1.5
