The question isCalculate the root mean square velocity of the following gases at 25°C a) H2 b) O2 c) Xe (M = 131.3) I used the equation: V=(3RT/M)1/2 I wasn't sure whether to use the R=0.0821 or 8.314 so I tried them both out and couldn't get the right solutions (as ...
To solve the problem, we need to find the root mean square (RMS) velocity of gas molecules when the molecular weight is doubled and the absolute temperature is halved. 1. Understand the Formula for RMS Velocity: The root mea

the main problem i am having here is units, and i am getting really frustrated, because i am a chem major, and this is chemistry! in order to solve for the root mean square speed, i said, based on the above relationships, RT/M = p/d so i plugged into vrms= sqrt (3p/d) BUT ...
What is the root mean square velocity of the molecules in a sample of oxygen gas at 0 °C and 100 °C? Solution: Root mean square velocity is the average velocity of the molecules that make up a gas. This value can be found using the formula: vrms= [3RT/M]1/2 where vrms= avera...
Really, the RMS calculation gives you root mean squarespeed,not velocity. This is because velocity is a vector quantity that has magnitude and direction. The RMS calculation only gives the magnitude or speed. The temperature must be converted to Kelvin and the molar mass must be found in kg ...
