QUESTION:

WF6 is one of the heaviest known gases. How much slower is the root-mean-square speed of WF6 than He at 300 K?

ANSWER:

Problem 10.79

$$ \mathrm{WF_{6}} is one of the heaviest known gases. How much slower is the root-mean-square speed of $$ \mathrm{WF_{6}} than $$ \mathrm{He_{2}}  at 300 K?

                                                              Step by Step solution

Step 1 of 2

The root-mean-square speed of gas can be calculated by the following formula.

                                                     $$ \mu_{\text{rms}} = \sqrt{\frac{\text{3RT}}{\text{M}}}

                                                            R = Universal gas constant

                                                           M = Molar mass of gas

                                                             T = Temperature
