What term is used for each of the following units: (a) a million liters; (b) a thousandth of a second; (c) a hundredth of a gram; (d) a tenth of a liter?

A construction team gives an estimate of three months to repave a large stretch of a very busy road with their core crew of 9 people. The government responds that it is too much of an inconvenience to have this busy road obstructed for three months, so the job must be completed in one month. If the relationship between construction time and crew members is inversely proportional, how many crew members does the construction team need if they are to complete the job in one month? Express your answer as an integer.

1) A student measures 7.45 cm³ of chloroform using a glass syringe. Given that the density of chloroform is 1.48 g/mL, and the molar mass is 119.38 g/mol, how many moles of chloroform did the student measure?

The speed of light is (2.998e8m/s) How far does light travel in 4.0μs? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.

Enter your answer in the provided box. The radius of a copper (Cu) atom is roughly 1.3 ×10−10 m. How many times can you divide evenly a 7147−cm long piece of copper wire until it is reduced to two separate copper atoms? (Assume there are appropriate tools for this procedure and that copper atoms are lined up in a straight line, in contact with each other. Round off your answer to an integer.)

What is the maximum mass of pure lead that could be extracted from 55.0 g of galena, a lead ore with the chemical formula PbS? Be sure your answer has a unit symbol, if necessary, and is rounded to the correct number of significant digits.

A 0.790 gram sample of copper is carried through the steps of an experiment. At the completion of the last step of the experiment, 0.314 grams of copper are recovered. What is the percent recovery of the copper metal? Give your answer in in decimal format.

The volume of water in large scale reservoirs is often measured in units of an acre-foot, which is the amount of water covering one acre of surface to a depth of one foot. An acre-foot is equivalent to 43,560 ft³. A particular water tower in town was constructed to hold 2.95 acre-feet of water. What is the volume of water in liters that the water tower will hold? ( 1 US liquid gallon = 231 cubic inches, 3.785 liters = 1 US liquid gallon)

Water has a density of 1.00g/mL. How many teaspoons of water are represented by 40,500 molecules of water. Use dimensional analysis.

A major component of gasoline is octane C8H18 . When liquid octane is burned in air it reacts with oxygen O2 gas to produce carbon dioxide gas and water vapor. Calculate the moles of carbon dioxide produced by the reaction of 0.055mol of octane. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.
