WebExpert Answer. 100% (1 rating) Transcribed image text: A large brine tank containing a solution of salt and water is being diluted with fresh water. The relationship between the elapsed time, t, in hours, after the dilution begins, and the concentration of salt in the tank, S (t), in grams per liter (g/1), is modeled by the following function. WebMay 3, 2024 · OD is a base-10 logarithm scale. So for example, if you dilute by 10x then the diluted OD will be 1 less than ( not 1/10th) of the undiluted OD. The original OD should be. 1.58 + log (7) = 1.58 + 0.85. =2.43. However, you should have been able to measure OD 2.43 in the original sample.

WebDose-response data are typically graphed with the dose or dose function (eg, log 10 dose) on the x-axis and the measured effect (response) on the y-axis. Because a drug effect is a function of dose and time, such a graph depicts the dose-response relationship independent of time. Measured effects are frequently recorded as maximal at time of ... http://vertassets.blob.core.windows.net/download/ec6cf02b/ec6cf02b-d7c7-430e-8c57-66fbac478f59/turbiditysuspendedsolids.pdf

WebThe rate of reaction is measured by dividing 1 by the time taken for the reaction to take place. Number of moles of sulphur used: n= m/M n= 8/32 = 0.25 mols Discussion: You can see from the graph that as concentration increases, the time taken for the solution to go cloudy decreases. WebQuantitative Analysis. In a GC chromatogram, the size and area of the component peak are proportional to the amount of the component reaching the detector. Here, we describe a quantitative analysis investigating the concentration of component A in an unknown sample. First, 1 μL of the unknown sample is analyzed, and the area of the peak for ...

WebOften, a worker will need to change the concentration of a solution by changing the amount of solvent. Dilution is the addition of solvent, which decreases the concentration of the solute in the solution. Concentration is the removal of solvent, which increases the concentration of the solute in the solution. (Do not confuse the two uses of the ... WebIn physics and relativity, time dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them (special relativistic "kinetic" time dilation) or to a difference in gravitational potential between their locations (general relativistic gravitational time dilation).When unspecified, "time dilation" usually refers to …
