De Broglie's Wavelength

Question: Calculate the De Broglie wavelength for a hydrogen atom at room temperature (300K).

So far, the only equation I know/have used for De Broglie wavelength is lambda=h/(mv). However, I am not exactly sure how to incorporate the information that the hydrogen atom is at room temperature into any equation I know of for figuring out either the de broglie wavelength or the speed of a hydrogen atom. Please give me some hints on how to approach this question! Thanks!

Use the rms speed of the hydrogen atoms for v.
