Homework Statement
A deuteron is the nucleus of a hydrogen isotope and consists of one proton and one neutron. The
plasma of deuterons in a nuclear fusion reactor must be heated to about 300 million K.
(a) What is the RMS speed of the deuterons? Is this a significant fraction of the speed of light c =
3 x 10^8 m/s?
(b) What would the temperature of the plasma be if the deuterons had an RMS speed equal to
0.10 c?
R=8.314; T=300E6K
Homework Equations
v[itex]_{rms}[/itex]=[itex]\sqrt{\frac{3RT}{M}}[/itex]
The Attempt at a Solution
I know how to solve this, but I don't get the first part of the question. how do you find M? I tried M=1.008, but that doesn't make sense.
