I am having troubles with how to approach this question..help would be great!  ;D

Methane (CH4) gas contains a small % of He. Calculate the % Volume of He if the density is 0.70902 g/L at 273 K and 1.000 atm?

Molar ratio of ideal gases is identical with their volume ratio. What is a density of gas containing x He and (1-x) CH4?
