(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1) A container is filled with a mixture of nitrogen and oxygen. What is the ratio of the rms speed of oxygen molecules to that of a notrigen molecules? (molar mass of oxygen = 32 g/mol; molar mass of nitrogen = 28 g/mol)

2) By what factor does the rms speed of neon molecules increase if their temperature increased by a factor of 4?

2. Relevant equations

rms= squared, mean, root.

1/2mv²=3/2KT where K = 1.83 x 10^-23 (Boltzmann's constant)

average velocity vectors of molecules = 0

3. The attempt at a solution

I'm completely clueless as to how to answer this question.
