The volume of a gas in discharge tube is...

The volume of a gas in discharge tube is `1.12 xx 10^(-7)` ml, at `0^(@)C` and 1 atm. The number of molecule of gas in the tube is-

A

`3.01xx10^(4)`

B

`3.01xx10^(15)`

C

`3.01xx10^(12)`

D

`3.01xx10^(16)`

Text Solution

Verified by Experts

The correct Answer is:
C
`"22,400 ml"-6.023xx10^(23)" moleculear"`
`1.12xx10^(-7)" ml"-`?
`=(1.12xx6.23xx10^(-7)xx10^(23))/(2.24xx10^(4))`
`=3.01xx10^(12)`
