Concept explainers
(a) Referring to Problem 1.119. calculate the total volume (in liters) of air an adult breathes in a day. (b) In a city with heavy traffic, the air contains
Interpretation:
The volume of air and carbon monoxide intake of an adult, in a day, is to be calculated.
Concept introduction:
A conversion factor is used to convert one unit into another.
The appropriate conversion factor for any equality is selected in such a way that it results in the proper unit cancellation.
The conversion factors for this are
1hr = 60 min. The conversion factors for this are
Answer to Problem 120AP
Solution:
a)
b)
Explanation of Solution
a)
Given information:
Number of breaths per minute is 12. The volume of air per breath of a resting adult is 500 mL.
Explanation:
An adult takes in 500mL of air per breath. The conversion factor for this is
Number of breaths per minute is 12.
1 min = 12 breath
The conversion factor for this is
Multiply
Multiply
Convert volume to liters by multiplying the calculated volume by the conversion factor
Volume of air breathed in a day is
b)
Given information:
Air contains
Explanation:
An adult breathes 8640 liters of air in a day.
One liter of air contains
The conversion factor to find the volume of carbon monoxide is
Multiply
Volume of carbon monoxide is

- 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?arrow_forwardA 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?arrow_forward2A. The average density of Earth is 5.52 g/cm3. What is its density in (a) kg/m3; (b) Ib/ft³? 2B. There are 2.60 x 1015 short tons of oxygen in the atmosphere (1 short ton = 2000 Ib). How many metric tons of oxygen are present (1 metric ton = 1000 kg)?arrow_forward
- Dimensional Analysis is a way of doing numerical "book-keeping" when converting quantities or performing calculations. • When converting quantities from one unit to another, conversion factors are used. Solving with Dimensional Analysis and Multiple Units: If I am in Canada where the price of gas is $1.022 USD·L1, how much will it cost me to fill up my gas tank if I travelled 125 km? • Let's also assume that my car gets an average of 30.0 miles/gallon.arrow_forwardContainer A and Container B were filled completely with chicken powder. The total mass of 1/3 of the chicken powder in Container B and 1/11 of the chicken powder in Container A was 570 g. If 5/11 of the chicken powder in Container A was poured out, the total mass of the chicken powder in both containers became 2.28 kg. How much chicken powder was in (a) Container A in grams? (b) Container B in grams?arrow_forwardA metal object of an irregular shape has a mass of 31.5 grams. When the metal is added to water in a graduated cylinder, the volume of water increases from 5.28 mL to 7.61 mL. (A) How much water does the metal displace? (B) Calculate the density of the metal.

- A gasoline station in Manila, Philippines, charges 38.46 pesos per liter for unleaded gasoline at a time when one U.S. 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?arrow_forwardCopper:(a) Suppose you have a cube of copper metal that is 0.236 cm on a side with a mass of0.1206 g. If you know that each copper atom (radius = 128 pm) has a mass of 1.055 ×10–22 g (you will learn in Chapter 2 how to find the mass of one atom), how manyatoms are there in this cube? What fraction of the cube is filled with atoms? (Orconversely, how much of the lattice is empty space?) Why is there “empty” space in thelattice?(b) Now look at the smallest, repeating unit of the crystal lattice of copper.Knowing that an edge of this cube is 361.47 pm and the density of copper is 8.960g/cm3, calculate the number of copper atoms in this smallest, repeating unitarrow_forwardA sample of tap water contains 1.95 x 103 ppm CaCO3(aq).
