APPLY 1.6 You are beachcombing on summer vacation and find a silver bracelet. You take it to the jeweler and he tells you that it is silver plated and will give you $10 for it. You do not want to be swindled so you take the bracelet to your chemistry lab and find its mass on a balance (80.0 g). To measure the volume you place the bracelet in a graduated cylinder (Figure 1.8) containing 10.0 mL of water at 20OC The final volume in the gradu- ated cylinder after the bracelet has been added is 17.61 ml.. The density of silver at 20OC is 10.5 g/cm3 and 1 cm3= 1mL. What can you conclude about the identity of the metal in the bracelet?

If Dallas and Los Angeles were connected by such a train, how long would it take to travel nonstop between these cities (a distance of 1490. miles)?arrow_forward1-89 Consider butter, density 0.860 g/mL, and sand, density 2.28 g/mL. (a) If 1.00 mL of butter is thoroughly mixed with 1.00 mL of sand, what is the density of the mixture? (b) What would be the density of the mixture if 1.00 g of the same butter were mixed with 1.00 g of the same sand?arrow_forward1-82 When the astronauts walked on the Moon, they could make giant leaps in spite of their heavy gear.

- A sample of a bright blue mineral was weighed in air, then weighed again while suspended in water. An object is buoyed up by the mass of the fluid displaced by the object. In air, the mineral weighed 7.35 g; in water, it weighed 5.40 g. The densities of air and water are 1.205 g/L and 0.9982 g/cm3, respectively. What is the density of the mineral?arrow_forward1-98 The antifreeze-coolant compound used in cars does not have the same density as water. Would a hydrometer be useful for measuring the amount of antifreeze in the cooling system?arrow_forward1-31 In the SI system, the second is the base unit of time. We talk about atomic events that occur in picoseconds (10-12 s) or even in femtoseconds (10-15 s). But we don’t talk about megaseconds or kiloseconds; the old standards of minutes, hours, and days prevail. How many minutes and hours are 20. kiloseconds?arrow_forward

The rate of flow is 150 gtts/min, and the IV administration set delivers 20. gtts/mL, where the unit “gtts” stands for drops of liquid. What is the running time in minutes?arrow_forwardA solution is prepared by dissolving table salt, sodium chloride, in water at room temperature. a Assuming there is no significant change in the volume of water during the preparation of the solution, how would the density of the solution compare to that of pure water? b If you were to boil the solution for several minutes and then allow it to cool to room temperature, how would the density of the solution compare to the density in part a? c If you took the solution prepared in part a and added more water, how would this affect the density of the solution?arrow_forwardWhat is the difference in surface area between two circles, one of radius 7.98 cm, the other of radius 8.50 cm? The surface area of a circle of radius r is r2. Obtain the result to the correct number of significant figures.arrow_forward
