Question on: JAMB Chemistry - 2013
The rate of diffusion of a gas Y is twice that of Z If the relative molecular mass of Y is 64 and the two gases diffuse under the same conditions, find the relative molecular mass of Z
A
32
B
4
C
8
D
16
Ask EduPadi AI for a detailed answer
Correct Option: D
(\sqrt{y}) = 2x
(\sqrt{Z}) = x
(\frac{rz}{ry}) = (\sqrt{\frac{my}{mz}})
(\frac{2x}{x}) = (\sqrt{\frac{64}{mz}})
(\frac{4}{1}) = (\frac{64}{mz})
mz = (\frac{64}{4})
mz = 16
