The correct answer is option e.
Explanation:
The formula used for root mean square speed is:
where,
= root mean square speed
k = Boltzmann’s constant =
T = temperature
M = Molar mass
= Avogadro’s number =
Root mean square speed of carbon dioxide molecule:
Temperature of the mixture = T =?
Molar mass of carbon dioxide = 44 g/mol = 0.044 kg/mol
T = 533.87 K
Root mean square speed of nitrogen molecule:
Molar mass of nitrogen = 28 g/mol = 0.028 kg/mol
689 m/s is the root-mean-square speed of the nitrogen molecules in the sample.
