Correct answer is 13:3 or 13/3
Explanation
Kinetic theory of gases
it is stated that,
Kinetic theory of gases also known as kinetic molecular theory.
It basically explains hypothetical behavior of ideal gas.

according to the kinetic molecular theory,
pV≅mv²/2
p'VpV=m'V'²/mV²
m'/m=p'/p(v/v')²=4/3(1/1/2)²=16/3
ratio of Δm to m is given by,
Δm/m=m'-m/m=m'/m-1=13/3
therefore,
Δm is change in mass of gas molecules,
and m is initial value of mass.

therefore 13/3 is the correct answer
