Oxygen gas (O2) is stored in steel cylinders. Assume we have 95.4 mol O2 stored in a 28-L cylinder at 25 oC. Use the van der Waals equation to calculate the pressure (in bar). [for O2(g), a = 137.8 and b = 0.0318]
Initially, at a temperature T, and a molar volume vi, a van der Waals gas undergoes a change of state to the final temperature T2 and the molar volume V2. The van der Waals gas is characterized by the two parameters a and b (cf. Eq. (3.3)). a. Show that the change in molar entropy is As = c, In 72 + R In º2 = (3.62) 01 - 6 b.

Use the van der Waals equation and the ideal gas equation to calculate the volume of 1.000 mol of neon at a pressure of 500.0 bar and a temperature of 355.0 K. (Hint: One way to solve the van der Waals equation for V is to use successive approximations. Use the ideal gas law to get a preliminary estimate for V ITS 500BAR use bar please not ATM
Ethane is held at 300 K and 200 atm. Solve for the molar volume under these conditions using (i) ideal gas, (ii) the van der Waals equation of state, and (iii) the Soave-Redlich-Kwong equation of state.
