The maximum number of molecules is present in

Options

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

Answer

A

Explanation

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
