On a day with a temperature of 15 ∘C and a pressure of 780.0 torr , how many grams of peroxyacyl nitrates are found in the air above Los Angeles (1500 km3) if the concentration is 30.0 mol of peroxyacetyl nitrate per 1 billion moles of air (30 ppb)? The molar mass of the major peroxyacyl nitrate, peroxyacetyl nitrate, is 118.03 g/mol. One of the highest concentrations of peroxyacyl nitrates has been found in the Los Angeles (LA) basin at 30.0 mol of peroxyacetylnitrate per 1 billion moles of air (30 ppb), reaching its peak at mid-afternoon. Most of the pollution in the LA basin is created in an areaof only 3000 km² and the pollution depth below the inversion layer is normally about 500 m. This concentration was therefore found in1500 km³ of air above Los Angeles.

One way to determine the hardness of a water sample is to precipitate the calcium out of solution as a carbonate. The net ionic reaction for this precipitation is: Ca2+(aq) + CO32-(aq) → CaCO3 (s) A 1.00 L sample of water is drawn from a Phoenix, AZ well and 0.534 g of calcium carbonate is recovered using the above reaction. What was the Ca2+ concentration of the original water sample in ppm? Show your work and include units. Hint: ppm stands for parts per million, and in the case of an aqueous solution, this is equivalent to mg/L.
Potassium dichromate has several industrial applications. To determine the purity of the salt that will be used in different industrial processes, a sample mass equal to 2.660 g was dissolved and quantitatively transferred to a 500.00 mL flask. An aliquot of 25.00 mL of this solution was treated with excess KI and the released iodine was titrated with 0.1000 mol L-1 sodium thiosulfate, spending 27.00 mL. Calculate the purity of the analyzed salt. Data:K = 39.10 O = 16.00 Cr = 52.00 I = 126.9 S = 32.07

Children’s toys and jewelry were assessed for their contamination by potentially toxic elements (PTE). This includes traces of As (74.92 g/mol), Cd (112.4 g/mol), Pb (207.2 g/mol), and Zn (65.39 g/mol) among others. The concentrations of these PTEs were determined to characterize the subsequent health risks, and to possibly reinforce better legislation on the manufacturing of these products.
