Hi.
00:02
So we are to determine which of the given gases here adapt or will diffuse the slowest.
00:08
So we're given with hydrogen gas, helium, fluorine gas, xenon, bromine gas.
00:19
So we will use formula for root mean square speed, prms, and this is equivalent to the square two three multiplied by the gas constant are the temperature t over the molar mass of the gas.
00:32
So you can see from the this formula that the molar mass is inversely proportional to the speed, which means that a higher molar mass would result to a lower speed, while a lower molar mass would result to a higher speed.
00:51
So what we'll need to do is we'll calculate the molar mass of this gas first, h2, molar mass would be 2 .02.
00:58
That's grams per mole.
01:00
H .e.
01:02
That would be 4 grams per mole.
01:05
Just refer to the predictable for this.
01:07
F2, molar mass of fluorine is 19...
