The atmosphere contains about 5.2×10^15t of air. What mass in metric tons of carbon dioxide is in the atmosphere if the concentration of CO2 is 390 ppm ? Express answer with the appropriate units.

Concentration of CO2 in the Atmosphere Levels of carbon dioxide (CO2) in the atmosphere are rising rapidly, far above any levels ever before recorded. Levels were around 278 parts per million in 1800, before the Industrial Age, and had never, in the hundreds of thousands of years before that, gone above 300 ppm. Levels are now nearing 400 ppm. Table 1 shows the rapid rise of CO2 concentrations over the last 50 years, also available in CarbonDioxide.1 We can use...

5. a) The composition of a mixture of nitrogen and carbon dioxide gases is 30%-N, and 70%- CO2 by mole fraction. What is the mass fraction of the nitrogen constituent?b) Nitrogen (N2) at 150 kPa, 40°C occupies a closed, rigid container having a volume of 1 m3. If 2 kg of oxygen (O2) is added to the container, what is the molar analysis of the resulting mixture? If the temperature remains constant, what is the pressure of the mixture, in...

(8 pts) Carbon dioxide in the atmosphere dissolves in water to establish an equilibrium that can increase the acidity of aqueous solutions in the environment. This equilibrium is CO2 (g) ⇌ CO2 (aq), Kh = 3.1 * 10^2 at 25°C. Kh is called the Henry’s law constant, which relates the solubility of the gas CO2 in the aqueous solution, [CO2], to the partial pressure of CO2 over the solution, p(CO2): [CO2] (M) = Kh * p(CO2) (atm) During the preceding...

Between 1857 and 1992, carbon dioxide (CO2) concentration in the atmosphere rose from roughly 290 parts per million to 380 parts per million. Assume that this growth can be modeled with an exponential function Q=Q0×(1+r)t. Complete parts (a) and (b) below. a. By experimenting with various values of the growth rate r, find an exponential function that fits the data for 1857 and 1992. r= b. Use this exponential model to predict when the CO2 concentration will double its 1857...

(8 pts) Carbon dioxide in the atmosphere dissolves in water to establish an equilibrium that can increase the acidity of aqueous solutions in the environment. This equilibrium is CO2(g) = CO2 (aq), Kn= 3.1 x 10-2 at 25°C. Kh is called the Henry's law constant, which relates the solubility of the gas CO2 in the aqueous solution, [CO2), to the partial pressure of CO2 over the solution, p(CO2): [CO2] (M)= Kn · p(CO2) (atm) During the preceding decades, the atmospheric...

Given that the atmosphere has a mass of 5.1x1018 kg and the mole fraction of methane is 1.8 ppm(V) in the atmosphere the gas-phase reaction with OH. radicals (hydroxyl radicals) is the mechanism for removal of methane from the atmosphere. The first order rate coefficient for methane reaction from the atmosphere is 0.1 yr-1. Emissions from the surface of the earth is the source of methane to the atmosphere. a.) What is the mass of methane in the atmosphere? b.)...
