Calculate each of the following: (a) Mass fraction of Cl in calcium chlorate (b) Mass fraction of N in dinitrogen trioxide Problems in Context 3.24 Oxygen is required for the metabolic combustion of foods. Calculate the number of atoms in 38.0g of oxygen gas, the amount absorbed from the lungs in about 15 min when a person is at rest. 8.25 Cisplatin (right), or Platinol, is used in the treatment of certain cancers. CI- Calculate (a) the amount (mol) of com- pound in 285.3 g of cisplatin; (b) the number of hydrogen atoms in 0.98 mol of cisplatin. Pt - H- 3.26 Allyl sulfide (below) gives garlic its characteristic odor. Cal- culate (a) the mass (g) of 2.63 mol of allyl sulfide; (b) the number of carbon atoms in 35.7 g of allyl sulfide. H S- C- 3.27 Iron reacts slowly with oxygen and water to form a compound commonly called rust (Fe,03-4H,O). For 45.2 kg of rust, calculate (a) moles of compound; (b) moles of Fe,O3; (c) grams of Fe. 3.28 Propane is widely used in liquid form as a fuel for barbecue grills and camp stoves. For 85.5 g of propane, calculate (a) moles of compound; (b) grams of carbon. 3.29 The effectiveness of a nitrogen fertilizer is determined mainly by its mass % N. Rank the following fertilizers, most ef- fective first: potassium nitrate; ammonium nitrate; ammonium sulfate; urea, CO(NH2)2.
