Question

There is a tire that has a volume of 35 L, 38 atm, and a temperature of240 K. How many moles of air is in the tire?

Answer 1

In this question, we have to calculate how many moles of air is in a tire with this following setup of data:

35 L

38 atm

240 K

In order to find the number of moles, we will be using the Ideal gas law formula, which is:

PV = nRT

Where:

P = pressure, 38 atm

V = volume, 35 L

n = number of moles

R = gas constant value, 0.082

T = temperature, 240 K

Now we add these values into the formula:

38 * 35 = n * 0.082 * 240

1330 = 19.68n

n = 1330/19.68

n = 67.6 moles of air are in this tire
