Question

calculate the pressure exerted by 10*23 gas molecules each of mass 10*-22 gram in a container of volume 1 litre the root mean square speed is 10*5 5 centimetre per second inverse..

plz reply fast..​?????

Answer 1

Answer:

According to the question, the pressure exerted by 1023

gas molecules each of mass 10−22

g in a container of volume one litre. The rms speed is 105cmsec−1

It is given that, n = 1023

M = 10-22 gram.  

 

V= 1 litre = 103 cm3

Urms=105 cmsec−1

PV = 1/3mnu2rms

P×10 3=1/3×10-22 ×1023× (105)2

P=3.3× 107 dynecm-2

Hence the answer is 3.3× 107 dynecm-2.
