If 1 L of `O_(2)` at `15^(@)C` and 750 mm pressure contains N molecules, the number of molecules in 2 litres of `SO_(2)` under the same conditions of temperature and pressure will be :

A

N

B

2N

C

`N//2`

D

4

Text Solution

Verified by Experts

The correct Answer is:
B
For `O_(2), PV = nRT`
`(740)/(760) xx 1 N xx R xx (273 + 15)`
For `SO_(2), PV = nRT`
`(740)/(760) xx 2 = N_(1) xx R xx (273 + 15)`
Dividing the two `N_(1) = 2N`
