Chapter 1, Problem 1.56E

he distance between atoms is sometimes given in pico-meters, where 1 pm is equivalent to 1 × 10^–12 m. If the distance between the layers of atoms in a particular compound is given as 568 pm, what is the distance in cm?

The engine in a boat has a displacement of 350in^3 what is the displacement of this in ft^3 in cm^3 in liters? Show your setups

Ethylene glycol, C2H6O2, is an ingredient of automobile antifreeze. Its density is 1.11 g/cm3 at 20 C. If you need 500. mL of this liquid, what mass of the compound, in grams, is required?

Suppose a room is 18 m long, 15 m wide, and the distance from floor to ceiling is 2.9 m. What is the room’s volume in cubic meters? In cubic centimeters? In liters?

A 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?

A sample of 18.11 grams of sodium hydroxide is weighed out on a balance and prepared to a volume of 2.00 x 102 mL in water.  What is the molarity of this aqueous solution of NaOH?  Express your answer to the correct number of significant figures and include the unit with your answer.
