6.022 x 10^23, the number of atoms or molecules in 1 mole of a substance. Proportionality Constant (R) Constant in the ideal-gas equation, relating the pressure, volume, temperature, and number of moles of a gas. Molar Volume Volume occupied by one mole of an ideal gas at standard temp...
A group additivity method has been generated which makes it possible to estimate, from the structural formulas alone, the energy of vaporisation and the molar volume at 25掳C of many nonpolar organic liquids. From these two parameters and appropriate thermodynamic relationships it is then possible ...

composition behavior of aqueous LiBr and of (Li, K, Na)NO3 mixtures; partial excess and molar volume-temperature-composition of aqueous LiBr and of (Li, K, Na)NO3 mixtures; partial excess and integral molar enthalpy-temperature-composition of aqueous LiBr; phase equilibria of NaOH in aqueous...
100 grams of liquid water at 298.15K is injected into a 1m^3 vessel. The temperature is maintained at 298.15K. Water vapor behaves as an ideal gas and the liquid water has a vapor pressure of 3164.396 Pa. The molar volume of water is 18.079E-6 m^3/mol, the molar mass of water is...
Two optimization approaches to correct the physical limitations of the Lee–Kesler–Plöcker equation of state for the application to long-chain hydrocarbons are presented. The quality of the approaches is evaluated by comparisons with experimental data and reference equations of state. The calculation...
Calculate the molar heat capacities at constant volume and constant pressure of the gas. (Exercise :Atkins physical chemistry 8th p.p71 2.12 (a) Answer : Cp,m = 30 J /K mol and Cv,m =22 J /K mol) To start this question,
A new three-parameter equation is obtained that relates gas liquid chromatographic retention indices for nonpolar and weakly polar substances such as hydrocarbons to their total solubility parameters, molar volume and the number of carbon atoms by applying the expanded solubility parameters model to gas...
1 mol of ideal gas occupies 22.4 L at STP. 75.0 L CH4 * (1 mol / 22.4 L) = 3.348 mol CH4 molar mass of CH4 = 16.04 g / mol 3.348 mol CH4 * (16.04 g / mol) = 53.7 g CH4 We use 3 significant figures in the answer because 3 were given in the problem statement, "75.0" ...
In summary, the conversation is about a question regarding calculating the number of moles of O atoms in 13.27 g Mn(NO3)2. The solution involves finding the molar mass of the compound and using it to calculate the number of moles of the compound in 13.27 g. It is also mentioned that ...
