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
