Answer 2

Answer:

1:√14:√7.

Explanation:

Since, we know from the states of gases that the molar mass of any element is inversely proportional to the square root radius of the elements. So, here the elements radius will be in ratio inversely proportional to the square root of the molar masses.

So, r(N2):r(H2):r(He)=1/√(M(N2)):1/√(M(H2));1/√(M(He)) which on solving we will get that r(N2):r(H2):r(He) = 1/√14:1/√2:1/√4. Which on simplifying we will get 1:√14:√7.
