Chemistry XXI Air Properties We can apply these ideas to start quantifying some basic air properties and monitor the concentration of different substances in our atmosphere. The following table shows H (km) ρ (g/L) 0 0.283 0.653 0.265 1.11 0.254 2.07 0.231 3.65 0.196 4.83 0.173 6.85 0.139 8.25 0.115 12.5 0.069 Let′s think!

Unformatted text preview: can be calculated: M ( air ) = 28.97 g/mol. The density of dry air under STP is 1.292 g/L. How can we use this information to estimate the volume of 1 mol of air at STP? Lets think! Chemistry XXI Air Properties How many particles are present in 1 L of air? How many moles of particles is this? What is the mass of this number of particles? Lets think!...
