Question

maximum no. of atoms are present in
(A)11..2 liters of So2 at STP
(B)22.4 liters of helium
(C)2.0gms of oxygen
(D)11.2 liters of methane at STP​

Answer 1

Answer:

op. D

Explanation:

11.2 litres of SO2 = 0.5 moles of SO2 = 0.5 x 64 = 32 gm

22.4 litres of He = 1 mole of He = 4 gm

2 gm of O = (1/32) mole of O

11.2 litre of methane = 0.5 mole of methane

no. of atoms = no. of moles x no. of atoms in one

molecule x Avogadro's no.

In this way, you will find that option D is correct.
