Volume moles

Here, k is the reaction rate constant, which is a function of temperature only Ca, Cb are the concentrations of the reactants A, B (moles/volume) a is the order of reaction, with respect to A (3 is the order of reaction, with respect to B (a + p) is the overall order of the reaction.

The mole (volume) fraction of acetone (C3H60) as a vapor in air is 6 %. This condition is uniform throughout a chamber of volume 20 m3. Air is supplied at 0.5 m3/s and the resulting mixture is withdrawn at the same rate. Assume that the mixture always has a uniform concentration of acetone for the chamber. Assume the gas density of the mixture is nearly that of pure air, 1.2 kg/m3. How long does it take to reduce the acetone mole fraction to 2 % ... 

We seek to describe the time-dependent behavior of a metabolic network that consists of m metabolic reactants (metabolites) interacting via a set of r biochemical reactions or interconversions. Each metabolite S, is characterized by its concentration 5,(f) > 0, usually measured in moles/volume. We distinguish between internal metabolites, whose concentrations are affected by interconversions and may change as a function of time, and external metabolites, whose concentrations are assumed to be constant. The latter are usually omitted from the m-dimensional time-dependent vector of concentrations S(t) and are treated as additional parameters. If multiple compartments are considered, metabolites that occur in more than one compartments are assigned to different subscripts within each compartment.

Clausius-Mossotti equation). In this expression, V designates the mole volume and Ae, Be, Cf,... are the first, second, third,... virial dielectric coefficients. A similar expansion exists for the refractive index, n, which is related to the (frequency dependent) dielectric constant as n2 = e (Lorentz-Lorenz equation, [87]). The second virial dielectric coefficient Be may be considered the sum of an orientational and a polarization term, Be = B0r + Bpo, arising from binary interactions, while the second virial refractive coefficient is given by just the polarization term, B = Bpo at high enough frequencies, the orientational component falls off to small values and the difference Be — B may be considered a measurement of the interaction-induced dipole moments [73],...

MOLE VOLUME. A mole of gas will occupy a definite volume under definite conditions regardless of the nature of the gas. This definite volume is called the mole volume. Under a pressure of 760 ton and at n temperature of 0°C, a gram-mole of gas will occupy 22.41 liters. This situalion also applies to a mixture of gases. A pound-mole of gas will occupy 359 cubic feel at a pressure of 760 totr and al a temperature of 32°F (0°C). 

Therefore, it is relatively easy to convert volumes of gases into moles and moles of gases into volumes using the following relationship number of moles = volume of the gas (in dm3 at rtp) of a gas 24 dm3... 

The units for Cp can vary. The most common units are in the form of mass/volume, such as pg/mL or ng/mL. This chapter exclusively uses Cp with mass/volume units. Very rarely, Cp is encountered in the chemist-familiar moles/volume format like pM or nM. 

This problem starts out as an application of mole volume. If we had 100 moles of the mixture, then we would have 84 mol CH4, 10 mol ( 2 Ip, 3molC3Hs, and 3 mol N2. We can calculate the amount of natural gas in 100 moles of the mixture by utilizing the molecular weights.
