How do I explain my reasoning for G29?

F60 Fundamentals G.26 Refer to Exercise G.25. How many successive tenfold dilu- tions of the original solution will result in one molecule of X being left in 10 mL of solution? G.27 Concentrated hydrochloric acid is 37.50% HCl by mass and has a density of 1.205 g-cm3. What volume (in milliliters) of concentrated hydrochloric acid must be used to prepare 10.0 L of 0.7436 M HCl(aq)? G.28 You need 500. mL of 0.10 M AgNO3(aq). You have on hand 100. mL of 0.30 M AgNO3(aq), 1.00 L of 0.050 M AgNO3(aq), and lots of distilled water. Describe how you would prepare the desired solu- you would use. tion and what volume of each solution G.29 The concentration of toxic chemicals in the environment is often measured in parts per million (ppm) or even parts H.1 Representing Chemical Reactions H.2 Balanced Chemical Equations per billion (ppb). A solution in which the concentration of the solute is 3 ppb by mass has 3 g of the solute for every billion grams (1000 t) of the solution. The World Health Organization has set the acceptable standard for lead in drinking water at 10 ppb. You need to analyze some tap water for lead concentra- tion, but your equipment is able to detect lead in concentra- tions only as low as 1×108 mol-L¹. Is your equipment satisfactory? You can assume that in such dilute solutions the density of the solution is 1.00 g-cm3. Explain your reasoning. G.30 Refer to Exercise G.29. In 1992 the tap water in one-third of the homes in Chicago was found to have a concentration of about 10 ppb lead by mass. If you lived in one of these homes and drank 2 L of tap water at home each day, what is the total mass of lead you would have ingested per year? H Chemical Equations The growth of a child, the production of polymers from petroleum, and the digestion of food are all the outcome of chemical reactions, processes by which one or more sub- stances are converted into other substances. This type of process is a chemical change (Fundamentals A). The starting materials are called the reactants and the substances formed are called the products. The chemicals typically available in a laboratory are used in a particular reaction is it called a Thi rea ske de de p f
