P: 1

1. The problem statement, all variables and given/known data
Calculate the V_{rms} for U^{235}F_{6} at 375 degrees C. What % of the molecules have V_{rms}>500 m/s? I'm not entirely sure on what direction to go in, sadly I missed the day he covered making these graphs and doing these types of problems. I do have all the formulas though.....but again I'm not sure on how to use them. Any help would be much appreciated, Thank you. P.s. I talked to the teacher and he said it would have kg and joules as it's units, that's why I put the MM of U^{235}F_{6} in kg, hopefully I'm right. Haha. Thanks again. 2. The attempt at a solution 3(.08206)(648) <all this is under a square root .348988
