It is also worthy to remember that the molar diamagnetic susceptibility is independent of temperature and is always negative. Now once the molar diamagnetic susceptibility is known, the corrected paramagnetic susceptibility (χ. M P) can be obtained from equation (35). Nevertheless, χ. M P. should further be corrected for temperature-

Solution. In this case, p and xi are given, and (7.46) provides an implicit equation for T which needs to be solved numerically, for example, by iteration. A straightforward approach is to use the method from the previous example, and iterate on T until the bubble pressure is 5 bar (for example, using the MATLAB code below). We find T = 382.64 ...

Analysis of the molar mass of the unknown acid reveals differences based on the possible natures of the acid itself, more specifically, how many protons it donates in solution. If the acid is monoprotic, the molar mass was calculated to be 58.94 g/mol, 117.9 g/mol if diprotic, and 176.8 g/mol if triprotic. The molarity of the NaOH

These are related as in Equation 3, since by multiplying the concentration (“mmol/mL”) by the flow rate (“mL/min”) we get a measure of the amount of substance per unit time (“mmol/min”). For the quenching flow Q the same holds (Equation 4). We also introduce the flow ratio between B and A (RB/A) and do the same for Q and B.

Then, from the ideal gas equation, the molar concentration of A and B is the same, c A = c B = c = p/RT (R = gas constant) The equality of c A and c B to the total concentration c is appropriate because the gases are pure; thus in each compartment the concentration of the gas (A or B) must also equal the total concentration c.

Because the x-axis was plotted in μM, the eb (or k) actually equals 0.0250·106 = 25000 L/mol (2.50·104 L/mol, with proper sig figs). We can use this plot to find the concentration of an unknown solution of Bromophenol Blue.

When using a 1 cm cuvette, the pathlength is 1 and equation. 1 can be simplified to OD x Extinction Coefficient x sample dilution. For example, if an undiluted dsDNA sample measured in a 1 cm cuvette gives an OD 260 value of 0.9 OD, the dsDNA concentration would be calculated as: 0.9 OD 50 45 μg/ml DNA.
