Suppose that in 1619, a man bought a diamond worth the equivalent of $17. Suppose that the man had instead been able to put the equivalent of $17 in a bank at 3% interest compounded continuously. What would that $17 have been worth in 2005? In 2005, the $17 would have been worth $ (Do not round until the final answer. Then round to the nearest dollar as needed)

8D. Closure and interior in products Let X and Y be topological spaces containing subsets A and B, respectively. In the product space X x Y: 1. $(A \times B)^\circ = A^\circ \times B^\circ$. 2. $\overline{A \times B} = \overline{A} \times \overline{B}$. 3. Part 2 can be extended to infinite products, while part 1 can be extended only to finite products. 4. Fr$(A \times B) = [\overline{A} \times $Fr$(B)] \cup [$Fr$(A) \times B]$. 5. If $X_\alpha$ is a nonempty topological space and $A_\alpha \subset X_\alpha$ for each $\alpha \in A$, then $\prod A_\alpha$ is dense (see 7C) in $\prod X_\alpha$ iff $A_\alpha$ is dense in $X_\alpha$ for each $\alpha$.

Problem 1. The mass transport of "Pollutant A" will be examined in three different compartments (air, water, and soil) in a container closed to the atmosphere. At t = 10 min, the concentration of "Pollutant X" in air (p¹₀ A₁), water (p¹₀ A₂), and soil (w¹₀ A) are given as 3 mg/L, 4 mg/L, and 0.1 mg/g, respectively. Some other information for "Pollutant X" is given in the following table: Air (Vₐ = 8 L) p¹₀ A₁ = 3 mg/L Water (Vw = 3 L) p¹₀ A₂ = 4 mg/L Soil particles (m = 50 g) w¹₀ A = 0.1 mg/g Additional information for Pollutant X: Henry's constant (H) = 0.1 Lw/La Soil-water equilibrium constant (KA₂) = 0.025 Lw/g One-film air phase mass trans. Const. (KAI) = 0.2 m/min One-film water phase mass trans. Const. (KA₂) = 0.004 m/min Physical properties of compartments: Depth of air (hₐ) = 25 cm Volume of air (V₂) = 8 liters Volume of water (VW) = 3 liters Mass of soil (m) = 50 grams Based on the information given in the problem: a) Calculate the total mass of "Pollutant X" in the container as grams. (10p) b) Determine the direction of mass transport for Pollutant X between "water and air" and "water and soil" at t = 10 min. (10p) c) Calculate the flux for the mass transport of "Pollutant X" between water and air phases as mg/m².min at 10 min. (15p) d) Calculate the equilibrium concentrations of Pollutant X in air, water, and soil phases (p A₁, p A₂, and w A) when the whole system reaches equilibrium. (15p) e) If the water phase concentration at 30 min (p₃₀ A₂) from t = 0 is 5 mg/L, calculate the concentration of "Pollutant X" in air at t = 30 min (p³₀ A₁). (20p)
