Independent Variable here is ”Speed”, since the independent variable is defined as (what's the scientist changes or what changes on its own)... And in here, both cars were traveling at 60 mph ’at a certain point, so, one of them might speed up or stay behind/lower it's speed from the other, depending on it's driver’.
Dependent Variable here is ”Distance”, since the dependant variable is defined as (what s being studied/measured).
Answer:
9.28moles
Explanation:
Given parameters:
volume = 11.1L
pressure = 204atm
temperature = 24°C = 24 + 273 = 297K
Unknown:
Number of moles of air in the cylinder = ?
Solution:
To solve this problem, we apply the ideal gas equation;
PV = nRT
P is the pressure
V is the volume
n is the number of moles
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
Now insert the parameters and find n;
204 x 11.1 = n x 0.082 x 297
226.4 = 24.4n
n = 9.28moles
