What mass of carbon dioxide is present in 1.00 m3 of dry air at a temperature of 15 ∘C and a pressure of 689 torr?
Pressure, “P” = 689 torr = 91859.1 Pa
Volume, “V” = 1 m3 = 1000 L
Temperature, “T” = “15^{omicron}” C = 288 K
Molar mass of CO2, “M” = 44 g/mol
From Ideal gas equation,
“PV=nRT”
“Rightarrow n=dfrac{PV}{RT}”
“Rightarrowdfrac{m}{M}=dfrac{PV}{RT}”
“Rightarrow m=dfrac{MPV}{RT}”
“Rightarrow m=dfrac{44times91859.1times1000}{8.314times10^3times288}”
“Rightarrow m=1687.99approx1688g”
