The maximum number of molecules is present in:-

A

`15 L H_(2)` gas at STP

B

5 L of `N_(20)` gas at STP

C

`0.5G H_(2)` gas

D

`10g" of " O_(2)` gas

Text Solution

Verified by Experts

The correct Answer is:
A
No. of molecules `= (15)/(22.4)xx N_(A) `
No. of molecules `=(5)/(22.4)xx N_(A)`
No. of molecules` = (0.5)/(2)xxN_(A)`
No. of molecules` = (10)/(32)xxN_(A) `
Hence 15 L `H_(2)` will have maximum munber of molescules
