The US environmental protection agency standard for coating beverage cans allows 0.29, 0.46 and 0.89 kilograms of VOC emission per liter of solids deposited for the two kinds of outside coating and one kind of inside coating in a standard two-piece beverage can. The coatings consist of solid polymers, plus pigments, dissolved in VOC solvents. The solids fraction, by weight of the paints and varnishes varies from about 20 percent to about 40 percent.
a. If we assume that the 0.29 kg/L restriction applies to a paint with 40 percent solids, what fraction fo the solvent VOC must be captured fo destroyed to meet this standard? (Assume that both solids and solvent have a density of 1 g/cm3)
b. VOC regulations in LA restrict the solvent emission from painting to 0.25 kg/L of solids. If you are a manufacturer of paints for outdoor use in LA, what are your possible ways of complying with this regulation?

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
