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?
For the pin shown in Fig. 2.5, why is the third figure determined for the length of the pin uncertain? Considering that the third figure is uncertain, explain why the length of the pin is indicated as 2.85 cm rather than, for example, 2.83 or 2.87 cm.

A hallow square metal tube has a measurement of 3.11 in for ewch side and a weight of 53.81g. The volume of empty space inside the tube was measured to be 1.95 in³. If the density of the metal used in constructing the tube is 9.22 m/mL, calculate the length of the tube in inches. Note that 1 in= 2.54 cm, 1cm³=1mL
Silicon for computer chips is grown in large cylinders called“boules” that are 300 mm in diameter and 2 m in length, asshown. The density of silicon is 2.33 g/cm3. Silicon wafersfor making integrated circuits are sliced from a 2.0-m bouleand are typically 0.75 mm thick and 300 mm in diameter.(a) How many wafers can be cut from a single boule?(b) What is the mass of a silicon wafer? (The volume of a cylinderis given by πr2h, where r is the radius and h is its height.)

(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?
