<p>Hey Dr. Pounds,</p>
<p>What's the best way to remember when to use .08206 OR 8.314
for R?</p>
<p>I keep getting confused when I need to use which number.</p>
<p> </p>
<p> </p>
<p>Thank you!</p>

Use 0.08206 whenever you are dealing with Gas Law problems (units of
Liters, Atmospheres, Degrees, and Moles). Use the other R whenever
you are dealing with energy in SI units (Joules, degrees, moles).
Remember that when computing the velocity of gas molecules you have
to use R in the SI units (because a Joule is a kg/(m sec^2).<br>
