(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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

2. Relevant equations

rms velocity , u = √(3RT/M )

3. 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
