(a)
Interpretation:
The number of microliters in
Concept introduction:
The conversion of one unit into another can be done using a proper conversion factor. Conversion factors are the ratios that relate the two different units of a quantity. It is also known as dimensional analysis or factor label method.
In the unit conversion problems, the given information is multiplied by the conversion factors to obtain the desired information. The unit conversion can be done as follows:

- Molecular distances are usually given in nanometers (1 nm = 1 109 m) or in picometers (1 pm = 1 1012 m). However, the angstrom () unit is sometimes used, where 1 = 1 1010 m. (The angstrom unit is not an SI unit.) If the distances between the Pt atom and the N atom in the cancer chemotherapy drug cisplatin is 1.97 , What is this distances in nanometers? In picometers?arrow_forwardA 2.0-mer volume of hydrogen gas combined with 1.0 liter of oxygen gas to produce 2.0 liters of water vapor. Does oxygen undergo a chemical or physical change?arrow_forwardWater 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?arrow_forward

Typically, 1.0 × 10−8gof a pheromone is sufficient to reach all targeted maleswithin a radius of 0.50 mi. Calculate the density of thepheromone (in grams per liter) in a cylindrical air spacehaving a radius of 0.50 mi and a height of 40 ft (volumeof a cylinder of radius r and height h is πr2h).arrow_forwardWater has a density of 0.96 mL-1 at its boiling point of 100 C under standard atmospheric pressure. The density of water vapor is about 1600 times less than the density of water under the same conditions. If a 1.00 L beaker of water was converted into water vapor at 100 C under standard atmospheric pressure, what would the volume (in L) of the water vapor be?arrow_forward
- In 2009, a team from Northwestern University and WesternWashington University reported the preparation of a new“spongy” material composed of nickel, molybdenum, andsulfur that excels at removing mercury from water. The densityof this new material is 0.20 g/cm3, and its surface area is1242 m2 per gram of material. (a) Calculate the volume of a10.0-mg sample of this material. (b) Calculate the surface area fora 10.0-mg sample of this material. (c) A 10.0-mL sample of contaminatedwater had 7.748 mg of mercury in it. After treatmentwith 10.0 mg of the new spongy material, 0.001 mg of mercuryremained in the contaminated water. What percentage of themercury was removed from the water?
