Four one litre flasks are seperately filled with the
gases hydrogen, helium oxygen and ozone at
same room temp. and pressure. The ratio of total
number of atoms of these gases present in the
different flasks would be -
(1) 1:1:1:1
(2) 1:2:2:3
(3) 2:1:2:3
(4) 2:1 3:2​

Answer 1

Answer:

option 3 ) 2:1:2:3

Explanation:

PV=nRT

as , given that value of P , V ,T is same for all gas, this give that number of moles of each gas are same

number of atom = number of mole × (avogadro' number) × atomicity

here , number of moles are same & avogadro's number is constant

this gives, => number of atoms are proportional to atomicity of gas

ratio of atoms = ratio of atomicity of(H2:He:O2 :O3)

=> ratio = 2:1:2:3
