The density of `O_(2)` is 16 at STP. At what temperature (in `.^@C`) its density will be 14 ? Consider that the pressure remais constant.

A

`50^@C`

B

`39^@C`

C

`57^@C`

D

`43^@C`

Verified by Experts

The correct Answer is:

B

`d_1T_1 = d_2T_2`
`16 xx 273 = 14 xx T_2`
`T_2 = 312K`
`T_2 = 312 - 273 = 39^@C`
