Comparing Molecules of Gases

1. The problem statement, all variables and given/known data
What volume of CH4 at 0°C and 1.00 atm contains the same number of molecules as 0.58 L of N2 measured at 35.0 °C and 1.50 atm?


2. Relevant equations
I think you just need to use Avogadro's Number and multiply by the molar mass?
I guess my question is what equation would you use?

3. The attempt at a solution
I haven't attempted the question due to lack of an equation.

You are probably looking for PV = nRT

thank you. i was trying that formula but was plugging in the wrong number for moles.

Remember you are doing the ratio of two of these, so you don't actualy need a value for R
