The maximum number of molecules are present in

A

15 L `H_(2)` gas at STP

B

5L of `N_(2)` gas at STP

C

0.5 g of `H_(2)` gas

D

10 g of `O_(2)` gas

Text Solution

Verified by Experts

The correct Answer is:
A
Maximum moles contain maximum molecules
15 L `H_(2)` gas `= (15)/(22.4)` mol `H_(2)` gas , 5L `N_(2)` gas `= (5)/(22.4)` mol `N_(2)` gas
0.5 g `H_(2)` gas `= (1)/(4)` mol `H_(2)` gas , 10 g `O_(2)` gas `= (1)/(3.2)` mol `O_(2)` gas
