Question

A box contains a mixture of two different ideal monoatomic gases, 1 and 2, in equilibrium at temperature T. Both gases are present in equal proportions. The atomic mass for gas 1 is m, while the same for gas 2 is 2m. If the $rms$ speed of a gas molecule selected at random is $V_{rms} = x\sqrt{\frac{K_gT}{m}}$) then x is ________ (Round off to 2 decimal places).

Answer 1

The correct answer is :1.50 to 1.50 or 1.57 to 1.59 (approx)
