To help farmers and gardeners, commercial fertilizers have a big three-number "NPK" label on the bag that gives the amounts of three key plant nutrients: nitrogen, phosphorus and potassium. For example, a bag of "10- 10- 10" fertilizer has 10% by mass nitrogen, 10% by mass potassium as potash (K,0), and 10% by mass phosphorus as phosphate (P205). Suppose a certain fertilizer has the following composition: ingredient percent by mass ammonium phosphate ((NH,), PO,) 37% (NH.),CO) urea 40% potassium chloride (KCI) 8% Inert ingredients 15% What should the first (nitrogen) number on the bag label be? That is, calculate the percent by mass of nitrogen in this fertilizer. Round your answer to the nearest percent. 山回

Cocaine (C17H21O4N) is a natural substance found in the leaves of the coca plant, which has been used for centuries as a local anesthetic and stimulant. Illegal cocaine arrives in the USA either as a pure compound or as the hydrochloride salt (C17H21O4NHCl). At 25oC, the salt is very soluble in water (2.50 kg/L), but pure cocaine is much less so (1.70 g/L). What is the maximum amount of salt (in gram) that can dissolve in 50.0 mL of water? [1 mark.] When a 25 mL aqueous solution that contains 62.50 g of the salt is treated with NaOH, the salt is converted to pure cocaine. How much water (in liters) is needed additionally to dissolve the formed pure cocaine? Round your final answer off to two decimal points. C17H21O4NHCl(aq) + NaOH(aq) → C17H21O4N(aq) + H2O(l) + NaCl(aq)

89 A number of compounds containing the heavier noble gases, and especially xenon, have been prepared. One of these is xenon hexafluoride (XeF6), which can be prepared by heating a mixture of xenon and fluoride gases. XeF6 is a white crystalline solid at room temperature and melts at about 325 K. A mixture of 0.0600 g of Xe and 0.0304 g of F2 is sealed into a 100.0-mL bulb. (The bulb is heated, and the reaction goes to completion. Then the sealed bulb is cooled back to 20.0°C. What will be the final pressure in the bulb, expressed in torr?

Pentaerythritol tetranitrate (abbreviated PETN, chemical formula C5H8N4O12) is an explosive material with a structure that is very similar to nitroglycerin. It is one of the components of plastic explosives such as Semtex. The explosion of PETN can be represented by: C5H8N4O12(s)→2CO(g)+4H2O(g)+3CO2(g)+2N2(g) A plastic explosive charge is formed into a cylinder about 30 cm long and about 2 cm in diameter. It weighs about 276 grams and is 58.5% PETN by mass. What is the total number of moles of gas produced when this plastic explosive charge explodes?
