Answer:
root mean square velocity of nitrogen at 25°c is 515 m/s
correct option is b) 515 m/s
Explanation:
given data
temperature = 25°c = 25 + 273 = 298 K
to find out
root mean square velocity of nitrogen molecules
solution
we know that root mean square velocity of gas is Vrms = .......................1
mass of gas = M
universal gas constant = R
temperature = T
and we know mass of nitrogen = 28 g = 28 × kg
Vrms =
Vrms =
Vrms = 515.22 m/s
root mean square velocity of nitrogen at 25°c is 515 m/s
correct option is b) 515 m/s
