Homework Help: chemistry

Posted by hellogoodbie on Monday, January 11, 2010 at 8:29pm.

I'm stumped again :(
the question is - A gas sprayed from an aerosol can effuses 5.06 times slower than oxygen.If the molar mass of oxygen is 32.g/mol, what is the molar mass of the unknown gas?

I dont know if I am doing the ideal gas law or grahams law or how to set it up. Please help. Thanks
