Specific molar volumes

Relationship Between Viscosity and Specific Molar Volumes... 

By neglecting the specific molar volume of the saturated liquid W in relation to that of the saturated vapor V, and by assuming the vapor phase to behave as an ideal gas, i.e., P V = RT, the above equation may be arranged into... 

Estimate the specific molar volume of liquid benzene using the Rackett equation (3.72). 

Fig. 9.5. Specific molar volumes of the folded (Vf) and unfolded (Vu) states of Snase as derived from densitometric measurements [15] (crosses, diamonds), pressure perturbation calorimetry [16] (open square), and spectroscopic high-pressure unfolding experiments [14] (filled squares). Dashed lines correspond to extrapolations...

An error of no more than about 1 % may be expected if the quantity Rt/P (the ideal specific molar volume) satisfies the following criterion ... 

The relationship between the density p (mass/volume), temperature, and pressure of an ideal gas can be obtained by first relating the specific molar volume, V (volume/mole), to the density. Using a specific set of units for illustration. 

You should also commit to memory the following values of the standard specific molar volume ... 

TEST What is Kay s rule How would you use it to calculate the specific molar volume of an equimolar... 

The specific internal energy of helium at 300 K and 1 atm is 3800 J/mol, and the specific molar volume at the same temperature and pressure is 24.63 L/mol. Calculate the specific enthalpy of helium at this temperature and pressure, and the rate at which enthalpy is transported by a stream of helium at 300 K and 1 atm with a molar flow rate of 250 kmol/h. 

In which Vj = MjfPj are the pure component specific molar volumes. Neglect any change in the pure component densities with temperature in the tempex- atiire.range 25-60X. 

Vw and Vl are the specific molar volumes of saturated vapor and saturated liquid, respectively AHy is the molar latent heat of vaporization... 

Note that V is the specific molar volume, defined as follows ... 

Unlike the dependencies of density deviation (from additive values) on system composition, correspondent dependencies of specific (molar) volume deviation from the additive values ... 

Interaction is accompanied by formation of the heteromolecular associates. It can be demonstrated by analysis of volumetric equations for the liquid mixed systems, data on volume compression, i.e., positive density deviation from additivity rule, and hence negative deviations of experimental specific molar volume from partial molar volume additivity rule. 

The radius, r, cm, of the solute molecule (which is assumed spherical) needs to be known in liquid-porous membrane/porous sorbent equilibrium. For relatively small molecular species, the specific molar volume of the solute will lead to...
