Molecular mass of an unknown liquid?

I have the mass of a condensed vapor, pressure, temperature while in boiling water, and the volume of the test tube it was in. I now need to calculate the molecular mass. Help?

Thanks!

Use pV = nRT to calculate n, the number of moles.

The molar mass = mass/n.
