The maximum number of molecules is present in

Options

(a) 15 L of H₂ gas at STP
(b) 5L of N₂ gas as STP
(c) 0.5 g of H₂ gas
(d) 10 g of O₂ gas

Correct Answer:

15 L of H₂ gas at STP

Explanation:

a)22.4 litre at STP contains 6.02 x 10²³ molecules of Hydrogen
15litre at STP contains = (15/22.4 ) x 6.02 x 10²³ molecules
b)22.4 litre at STP contains 6.02 x 10²³ molecules of Nitrogen
5 litre at STP contains = (5/22.4 ) x 6.02 x 10²³ molecules
c)2 g of hydrogen contains 6.02 x 10²³ molecules of hydrogen
0.5 g of Hydrogen contains = (0.5/2 ) x 6.02 x 10²³ molecules
c)32 g of oxygen contains 6.02 x 10²³ molecules of hydrogen
10 g of Hydrogen contains = (10/32 ) x 6.02 x 10²³ molecules
Thus (a) will have ma
