Question

Calculate the number of molecules in one litre of a gas at N.T.P. ,if mass of

each molecules is 4.55x10-25 kg and its rms velocity at N.T.P. is 350m/s

( atmospheric pressure , P= 1.013x105 N/m2

)​

Answer 1

Answer:

each molecules is 4.55x10-25 kg and its rms velocity at N.T.P. is 350m/s

( atmospheric pressure , P= 1.013x105 N/m2

P=0.001x10 N/m
