A gasoline station in Manila, Philippines, charges 38.46 pesos per liter of unleaded gasoline at a time when one US. dollar (USD) buys 47.15 pesos (PHP). The car you are driving has a gas tank with a capacity of 14 U.S. gallons and gets 24 miles per gallon. (a) What is the cost of unleaded gasoline in Manila in USD per gallon? (b) How much would a tankful of unleaded gasoline for your car cost in USD? (c) Suppose that you have only PHP 1255 (a day's wage for an elementary school teacher) and the car's tank is almost empty. How many miles can you expect to drive if you spend all your money on gasoline?

A 40-lb container of peat moss measures 14 * 20 * 30 in. A40-lb container of topsoil has a volume of 1.9 gal. (a) Calculatethe average densities of peat moss and topsoil in units ofg>cm3. Would it be correct to say that peat moss is “lighter”than topsoil? (b) How many bags of peat moss are needed tocover an area measuring 15.0 ft * 20.0 ft to a depth of 3.0 in.?
To identify a liquid substance, a student determined itsdensity. Using a graduated cylinder, she measured out a 45-mLsample of the substance. She then measured the mass of thesample, finding that it weighed 38.5 g. She knew that the substancehad to be either isopropyl alcohol 1density 0.785 g>mL2or toluene 1density 0.866 g>mL2. What are the calculated densityand the probable identity of the substance?

She then measured the mass of thesample, finding that it weighed 38.5 g. She knew that the substancehad to be either isopropyl alcohol (density 0.785 g/mL)or toluene (density 0.866 g/mL). What are the calculated densityand the probable identity of the substance? (b) An experimentrequires 45.0 g of ethylene glycol, a liquid whose densityis 1.114 g/mL. Rather than weigh the sample on a balance, achemist chooses to dispense the liquid using a graduated cylinder.What volume of the liquid should he use? (c) Is a graduatedcylinder such as that shown in Figure 1.21 likely to afford theaccuracy of measurement needed? (d) A cubic piece of metalmeasures 5.00 cm on each edge. If the metal is nickel, whosedensity is 8.90 g/cm3, what is the mass of the cube?

(a) A sample of tetrachloroethylene, a liquid used in dry cleaningthat is being phased out because of its potential to cause cancer,has a mass of 40.55 g and a volume of 25.0 mL at 25 °C. Whatis its density at this temperature? Will tetrachloroethylene floaton water? (Materials that are less dense than water will float.)(b) Carbon dioxide (CO2) is a gas at room temperature andpressure. However, carbon dioxide can be put under pressure tobecome a “supercritical fluid” that is a much safer dry-cleaningagent than tetrachloroethylene. At a certain pressure, the densityof supercritical CO2 is 0.469 g/cm3. What is the mass of a25.0-mL sample of supercritical CO2 at this pressure?
A 37.2-g sample of lead (Pb) pellets at 20°C is mixedwith a 62.7-g sample of lead pellets at the sametemperature. What are the final mass, temperature, anddensity of the combined sample? The density of Pb at20°C is 11.35 g/cm3
Using Two or More Conversion FactorsIt is often necessary to use several conversion factors in solving a problem. As an example,let’s convert the length of an 8.00-m rod to inches. The table on the back inside coverdoes not give the relationship between meters and inches. It does, however, give the relationshipbetween centimeters and inches 11 in. = 2.54 cm2. From our knowledge of SIprefixes, we know that 1 cm = 10-2 m. Thus, we can convert step by step, first from metersto centimeters and then from centimeters to inches:
Water has a density of 0.997 g>cm3 at 25 °C; ice has a densityof 0.917 g>cm3 at -10 °C. (a) If a soft-drink bottle whose volumeis 1.50 L is completely filled with water and then frozento -10 °C, what volume does the ice occupy? (b) Can the icebe contained within the bottle?
