Answer:
1050 K
Explanation:
vrms=3RTm−−−−√
v1v2=T1M1×M2T2−−−−−−−√
vHvN=THMH×MNTN−−−−−−−−√
7 = TH×282×300−−−−−√
49 = TH×28600
TH=49×60028=1050K

The temperature of
, at which the rms velocity of its molecules is seven times the rms velocity of the molecules of nitrogen at 300 K is 1050 K
Explanation:
The formula used for root mean square speed is:
where, = root mean square speed
R = gas constant
T = temperature
M = atomic mass of nitrogen = 28 g/mole
Now put all the given values in the above root mean square speed formula, we get:
For ,
