Hi here is a question I am having trouble with. I need help only on part c.
____________________________________________________________________________________________________________________________________________________________
Each time you inhale, you take in about 500 ml (two sigfigs) of air, each millileter of which contains 2.5 x 10^19 moleules. In delivering the Gettysburg Adress, Abraham Lincoln is estimated to have inhaled about 200 times.
a.) How many molecules did Lincoln take in?
My answer: 200 * (500 ml) * (2.5 x 10^19 molecules / 1 ml) =
2.5 x 10^24 molecules
b.) In the entire atmosphere, there are about 1.1 x 10^44 moleules. What fraction of the molecules in the Earth's atmosphere was inhaled by Lincoln at Gettysburg?
My Answer: (2.5 x 10^24)/(1.1 x 10^44)=
2.3 x 10^-20
c.) In the next breath that you take, how many molecules were inhaled by Lincoln at Gettysburg?
***I don't understand what this part of the question is asking for. How do I go about this?
Doing the same problem, and i don't either
I inhaled 500 ml(2.5 x 10^19 molecules/ 1 ml)= 1.25 x 10^22 molecules. in the entire atmosphere Lincoln fractionly inhaled 2.3 x 10^-20 molecules, so 1.25 x 10^22 x 2.3 x 10^-20 = 2.8 x 10^2 approximately.
In part c, the question is asking how many molecules were inhaled by Lincoln in the next breath that you take. To solve this, you need to determine the number of molecules inhaled by Lincoln in one breath and then compare it to the number of molecules inhaled in your next breath.
To calculate the number of molecules inhaled by Lincoln in one breath, you can use the same formula as in part a:
Number of molecules inhaled by Lincoln in one breath = 500 ml * (2.5 x 10^19 molecules / 1 ml)
Now, to find the number of molecules inhaled by Lincoln in your next breath, you need to know the volume of air you inhale with each breath.
Let's say you inhale 600 ml of air with each breath. To find the number of molecules inhaled by Lincoln in your next breath, you can use the same formula:
Number of molecules inhaled by Lincoln in your next breath = 600 ml * (2.5 x 10^19 molecules / 1 ml)
Remember to use the appropriate volume value for your next breath. Substitute this value into the formula to find the answer.
To understand part c of the question, let's break it down.
In part c, the question is asking how many molecules Lincoln inhaled in his next breath, given that he inhaled a certain number of molecules during his delivery of the Gettysburg Address.
To solve this, we need to know the number of molecules present in a single breath. The information given states that each milliliter of inhaled air contains 2.5 x 10^19 molecules.
To find the number of molecules in a single breath, we need to know the volume of air inhaled in a breath. Typically, a person inhales about 500 ml (or 0.5 liters) of air in one breath.
So, to calculate the number of molecules inhaled by Lincoln in his next breath, we can use the following conversion:
Number of Molecules = Volume of Air Inhaled * Number of Molecules per Milliliter
Substituting the values:
Number of Molecules = 500 ml * (2.5 x 10^19 molecules / 1 ml)
Now, you can plug these values into the equation and calculate the answer:
Number of Molecules = 500 ml * (2.5 x 10^19 molecules / 1 ml)
= 1.25 x 10^22 molecules
Therefore, Lincoln inhaled approximately 1.25 x 10^22 molecules in his next breath.
