What is the rms speed of nitrogen molecules contained in a 8.5 m3 volume at 3.5 atm if the total amount of nitrogen is 1900 mol ?

Explanation: Using ideal gas equation:

PV = nRT

P= pressure = 3.5 atm

V= volume =

n = no of moles = 1900

R= gas constant =0.0821 Latm\molK

R= gas constant = 8.314 J/Kmol

T= temperature = 190.7 K

M= molecular mass of nitrogen = 28 g/mol
