Homework Statement
A sample of an ideal gas is at a temperature of 320 K. The rms molecular speed at this temperature is measured as 1631 m/s. Calculate the mass of a molecule of this gas
Homework Equations
rms velocity , u = √(3RT/M )
The Attempt at a Solution
Given u = 1631 m / s
Temperature , T = 320 K
R = gas constant = 8.314 J/ mol . K
Molar mass of the gas molecule , M = 3RT / u 2
= 3 * 10^-3 Kg / mol
