Find the rms speed of the molecules of a sample of n2 (diatomic nitrogen) gas at a temperature of 38.7°c.

- rms speed of nitrogen gas is 526.93 m/s.

Solution:- The formula used to calculate the rms that is root mean square velocity is....

where, R is universal gas constant in terms of energy and it's value is 8.314 J/mol.K

T is kelvin temperature.

T = 38.7 + 273 = 311.7 K

M is molar mass and the molar mass of nitrogen gas is 28 g/mol. Need to convert it to kg/mol and so it becomes 0.028 kg/mol.

Let's plug in the values in the formula...

[tex]v_r_m_s = 526.93 m/s

the answer your looking for is c).
