Answer: The Answer is 18.7ml.
Explanation: Solved in the attached picture.
mol = 25/12
= 2.083 mol
1 mol = 6.02 × 10^23 atoms
2.083 mol = X
X = 2.083/1 × 6.02 × 10^23
= 1.254 × 10^24 atoms
The difference between the ideal pressure and the pressure calculated by the Van Der Waal equation is 2.08 atm.
<h3>What is the pressure?</h3>
In this problem, we are mandated to obtain the pressure both by the use of the ideal gas equation and then the use of the Van der Walls equation.
Using the idea gas equation;
PV = nRT
P = nRT/V
P = pressure
V = volume
n = number of moles
T = temperature
R = gas constant
P = 1 * 0.082 * (24 + 273)/0.5
P = 48.7 atm
Using the Van Der Wall equation:
P = RT/(V - b) - a /V^2
P = 0.082 * 297/(0.5 - 0.03219) - 1.345/(0.5)^2
P = 24.354/0.46781 - 1.345/ /0.25
P = 52 - 5.38
P = 46.62 atm
The difference between the ideal pressure and the pressure calculated by the Van Der Waal equation is; 48.7 atm - 46.62 atm = 2.08 atm
