Unformatted text preview: kg/m s 2 )(5.10 x 10 14 m 2 ) Force = 5.15 x 10 19 kg m /s 2 d. Mass of the atmosphere Force = (mass)(acceleration) therefore mass = Force/acceleration mass = (5.15 x 10 19 kg m/s 2 )/(9.8 m/s 2 ) note: this is the acceleration due to gravity mass = 5.26 x 10 18 kg or 5.26 x 10 21 g e. Moles in the atmosphere mol = (5.26 x 10 21 g)(1 mol/29 g) mol = 1.81 x 10 20 mol 3. Fraction of atmosphere which represents molecules from Caesar’s last breath: (0.075 mol)/(1.81 x 10 20 mol) = 4.14 x 1022 4. Moles of Caesar’s last breath in your last breath: Assume your breath holds 0.075 mol: (0.075 mol)(4.14 x 1022 ) = 3.11 x 1023 mol 5. Number of molecules: (6.022 x 10 23 molecules/mol)(3.11 x 1023 mol) = 18.7 molecules ( An even more disconcerting fact is that he probably had flatulence as well. )...
