Answer:
43.1atm is the pressure using gas law and 27.2atm using Van der Waals Law.
Explanation:
Ideal gas law is:
PV = nRT
<em>Where P is pressure in atm</em>
<em>V is volume = 4.00L</em>
<em>n are moles of the gas (For chlorine Molar Mass: 70.90g/mol):</em>
<em>500g * (1mol / 70.90g) = 7.052 moles</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is absolute temperature = 25°C + 273 = 298K</em>
To solve the pressure, P:
P = nRT/V
P = 7.052mol*0.082atmL/molK*298K / 4.00L
P = 43.1atm is the pressure using gas law.
Van der Waals equation is:
<em>Where a is 6.58L²atm*mol⁻²</em>
<em>b = 0.056Lmol⁻²</em>
Solving for pressure:
P = 172.323 / 3.6051 - 20.4866
P = 27.2atm using Van der Waals Law
Answer:
V₂ = 457.49 mL
Explanation:
Given that,
Initial volume,
Initial temperature,
Final temperature,
We need to find the final volume of the gas. The relation between the volume and the temperature of the gas is given by :
Put the respected values,
So, the final volume of the gas is equal to 457.49 mL.
