Which diffuses faster, the bad smell from a cat-pan due to ammonia or an expensive French perfume with an average molecular weight of 170 g/mol? How much fast does the fast one diffuse?

Answer 1

Ammonia has a molar mass of 17. It diffuses faster than perfume with a molar mass of 170.
(rate1/rate2) = sqrt (Mol mass 2/mol mass 2) or about sqrt(170/17) = about 3 times faster. You can work it out more accurately.

Answer 2

the answer is that ammonia has a less molar mass than that of perfume and therefore for that reason ammonia diffuses faster......and at the rate of 10 times faster than perfume.....

Answer 3

perfume
