help! I am trying to figure out how to convert from equation one to equation two. I have spent two hours on this and cannot figure it out. I would greatly appreciate if someone could help me out on this.

Equation1: v= sqr root (3RT/M) with R being the molar gas constant, M being the molecular weight and T being the temperature in Kelvin

Equation2: de broglie wavelength = (hNa)/ sqr root (3MRT) with Na being Avogadros number and h being Planck's constant and M,R,T being the same as above.

How do I get from equation 1 to equation 2.

Any help would be greatly appreciated.
