Which of the following is true about the number of molecules in A and B?

Answer»

Flask `A` contains EIGHT TIMES more molecules than flasks `B`.
Flask `B` contains eight times more molecules than flask `A`.
Both flasks contain an EQUAL number if molecules.
Flasks `A` contains four times more molecules than flasks `B`.

Solution : `n_(A)=(m)/(2)`, `n_(B)=(m)/(16)`, `(n_(A))/(n_(B))= 8 since`
`n_(A) prop N`, `:. (N_(A))/(N_(B))=8`
(`n=` number of moles)(`N=` number of molecules)
