At room temperature ratio of pressures of `CH_(4)` and `CO_(2)` kept in two separate containers of equal volume is `3:5`. Then two containers have equal number of-

Options

A. (a)moles
B. (b)electrons
C. (c )atoms
D. (d)molecules

Answer

C

Explanation

`P prop nimpliesn_(CH_(4))/(n_(CO_(2)))=3/5`
`implies("no. of atoms in container of" CH_(4))/("no. of atoms in container of" CO_(2))=(3xx5)/(5xx3)=1`
`implies` Both containers have equal no. of atoms
