Chemistry: Principles and Practice
- 1-85 In Japan, high-speed “bullet trains” move with an average speed of 220. km./h. 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_forward1.88 Legend has it that Archimedes, a famous scientist of Ancient Greece, was once commanded by the king to determine if a crown he received was pure gold or a gold—silver alloy. He was not allowed, however, to damage the crown (by slicing off a piece, for example). If you were assigned this same task, what would you need to know about both gold and silver, and how would you make a measurement that would tell you if the crown was pure gold?arrow_forwardA sample of vermilion-colored 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 18.49 g; in water, it weighed 16.21 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_forward
- 1-76 If the density of air is 1.25 10-3 g/cc, what is the mass in kilograms of the air in a room that is 5.3 m long, 4.2 m wide, and 2.0 m high?arrow_forwardRadio waves travel at the speed of light 3.00x10^8m/s. If you were to broadcast a question to the Mars rover spirit on Mars which averages 225,000,000 Miles from earth what is the maximum time that you would have to wait to receive a reply?arrow_forwardWhat is the mass of a cylinder of lead with a radius of 1 centimeter and a height of 3 centimeters, given that the density of lead is 11.4 (g)/(cm^(3))?arrow_forward
- A rectangular lead apron is placed over the chest of a patient while X-rays are being taken in a dental office. The apron measures 75.0cm by 50.0cm by 0.20cm. If the density of the lead is 11.3g/cm^3, what is the mass (in g) of the lead apron?arrow_forwardThe world record for the hundred meter dash is 9.58 s. What is the corresponding average speed in units of m/s, km/h, ft/s, and mi/h? At this speed, how long would it take to run 1.00×102 yards?arrow_forwardWhat is the density of copper (in g/cm3) if a rectangular bar measuring 0.60 cm in height, 2.04 cm in width, and 12.00 cm in length has a mass of 131.6 g?arrow_forward
- How many minutes will it take a car to travel 857 km if the car is moving at a constant speed of 25 mi/hr ?arrow_forward8. Your calculator gives you the number 1761.2868 as the volume (in cm^ 3) of a box 2.0 ft by 6.5 cm by 1.75 în. Since this number should reflect the precision of the physical measurements, how many significant figures will you record for the volume of the box? What is the volume of the box?arrow_forwardAn Amazon Prime delivery truck carrying COVID-19 vaccines from the Pfizer distribution center in Kalamazoo, MI to York College, NY makes a stop in Columbus, OH. The distance from Kalamazoo to Columbus is 236.7 miles and the total distance from Kalamazoo to York College is 835.4 miles. If the truck travels at 1.45 Km/min, how many hours will it take to arrive at York College after the stop in Columbus? Round your answer to the ones place.arrow_forward
