Question

14) The concentration of N20 at sea level is 334 ppb. a. Convert this to ppm. b. Calculate the mixing ratio of N20. c. Calcul

Answer 1

Answer #1

a)1ppb = 0.001ppm

334ppb = .334ppm

b)the mixing ratio of N2 = 0.78mol/mol , mixing ratio of O2 is .21mol/mol. the mixing ratio of N2O = 320*10^-9mol/mol

c) the number denity is the number of molecules of gas per unit volume of air.

number density of air , na = AvP/RT = (6.023*10^23)(1.013*10^5)/8.31*273

=2.689*10^25molecules m-3

number density of N2O = mixing ratio of N2O*na

= 320*10^-9*2.689*10^25

=8.6048*10^18
