- At the critical point for carbon dioxide, the substance is very far from being an ideal gas. Prove this statement by calculating the density of an ideal gas in g/cm3 at the conditions of the critical point and comparing it with the experimental value. Compute the experimental value from the fact that a mole of CO2 at its critical point occupies 94 cm3.Please don't provide handwritten solution ....You add 28 g of ice (H2O) at 0°C to 179 g of H20 (I) at 63°C at a constant pressure of 1.01 kPa. Calculate the final temperature in K. [AfusH°(H20) = 6.01 kJ mol""; Tfus=273.15 K; Cp.m(H20,)=75.3 J mol Kl; m(H20)=18.02 u].
- A gas mixture contains 4.5 mol Br, and 33.1 mol F,. (a) Compute the mole fraction of Br, in the mixture. (b) The mixture is heated above 150°C and starts to react to give BrFs: Br2(g) + 5 F2(g) –→ 2 BrF;(g) At a certain point in the reaction, 2.2 mol BrF5 is present. Determine the mole fraction of Br2 in the mixture at that point.I need the answer as soon as possibleWhat is the temperature in K of 0.795 mole of neon in a 2.00 L vessel at 4.32 bar?

- For ethane at 298.15 K, B = -186 cm³mol-¹ and C= 1.06x104 cm'mol². Use the formula B PVm = RT [1 1+ + Vm V2 m to calculate the pressure of 28.8 g of ethane in a 999 cm³ container at 298.15 K and the amount of atm in which it is far from the ideal value.Under constant-pressure conditions a sample of hydrogen gas initially at 47°C (320K) and 6700 mL is heated to 122°C (395K). What is the final volume?An open-end mercury manometer is to be used to measure the pressure in an apparatus containing a vapor that reacts with mercury. A 10-cm layer of silicon oil (SG = 0:92) is placed on top of the mercury in the arm attached to the apparatus. Atmospheric pressure is 765 mm Hg.(a) If the level of mercury in the open end is 365 mm below the mercury level in the other arm, what is the pressure (mm Hg) in the apparatus?(b) When the instrumentation specialist was deciding on a liquid to put in the manometer, she listed several properties the fluid should have and eventually selected silicon oil. What might the listed properties have been?
- 53. Given the critical pressure, Pc, and the critical pressure, Tc, for CO2 are 73.75 bar and 304.13 K, respectively. (i) Assuming CO2 is an ideal gas, CALCULATE the critical volume, Vc. (ii) Assuming CO2 is a van der Waals gas, CALCULATE Vc. (iii) Assuming CO2 is a Redlich-Kwong, CALCULATE Vc. (iv) COMPARE the obtained Vc values in (i)–(iii) with that of the true Vc value; that is 0.09407 L.(6) Calculate the molar volume of carbon dioxide at 400 K and 30 atm, given that the second virial coefficient (B) for CO2 is -0.0605 L•mol-1. Compare the result with that obtained using the ideal-gas law.
