What is molar extinction coefficient of bsa?
The molar extinction coefficient of BSA (bovine serum albumin) is approximately 43,824 M^(-1)cm^(-1) at a wavelength of 280 nm. This value is commonly used to quantify the concentration of BSA in a solution based on its absorbance at 280 nm.
Why molar extinction coifficient of KMNO4 is much higher than that of CoCl2?
Molar extinction coefficient is depend on intensity of the colour of solution.If the solution has high intensity of colour, molar extinction coefficient is high.So when considering CoCl2 and KMnO4, CoCl2 has low colour intensity. KMnO4 solution has much intense purple colour.Therefore its Molar extinction coefficient is high. By-Tharindu Chathuranga Ariyathilaka/Sri Lanka
How do we determine molar extinction coefficient using standard plots?
In the beginning, no you need not cull the special coefficient
What do you mean molar extinction co efficient what information can be obtain from it?
The molar extinction coefficient (also sometimes called molar absorbtivity coefficient) is a measure of how strongly a solution of a substance absorbs light (the value depends on the particular wavelength of light used). By passing light through a solution and determining how much of the light is absorbed, you can use the path length and molar extinction coefficient to determine the concentration of the solution.Look up "Beer-Lambert law" if you want details.
What increase absorbance of phenol in ethanol?
Possible factors that can increase the absorbance of phenol in ethanol are: increasing the concentration of phenol in the solution, using a higher path length cuvette for measurement, and selecting a wavelength for measurement where phenol has a higher molar absorptivity coefficient.
Could you please define the extinction coefficient?
The extinction coefficient can refer to a few different measures how strongly a distinct medium absorbs light at a particular wavelength. The two most commonly referred to are molar absorptivity (which measures absorption per molar concentration) and the mass attenuation coefficient (which measures absorption per mass density).
What is the Molar extinction coefficient of ADP?
The molar extinction coefficient of ADP at a specific wavelength varies depending on the solvent and experimental conditions. It is typically around 8100 M-1cm-1 at 259 nm for ADP in water. Make sure to consult a reliable source or perform your own measurements for accurate values.
How do you figure out molar heat of combustion of phenol at 25 degrees celsius?
The molar heat of combustion of phenol can be calculated by measuring the heat released when a known amount of phenol is completely burned in a calorimeter. The heat released is then used to calculate the molar heat of combustion using the mass of phenol burned and the molar quantity of phenol. This calculation can be done using the formula: heat released = molar heat of combustion x moles of phenol.
What is the molar extinction coefficient of cefotaxime at 257 nm?

What is the molar extinction coefficient for glucose at 510 nm?
I am not some one of this background and so please correct me if I am wrong. I think molar extinction coefficient will be very less and according to molecular structure of any molecule (bond vibration etc..,) only some wavelengths will have reasonable absorption and for glucose those wavelenghts are 1550-1850 nm; 6450-5400 cm(-1) (first overtone) 2000-2500 nm; 4000-5000 cm(-1) (combination). These are the spectral windows in which glucose has significant absorption.
What is the extinction coefficient of crystal violet?
The extinction coefficient of crystal violet is approximately 89,000 M^(-1)cm^(-1) at a wavelength of 590 nm. This value indicates the molar absorptivity of crystal violet at this specific wavelength, which is commonly used for measuring the concentration of crystal violet in solution using spectrophotometry.
What is the molarity if the absorbance is 0.6?
We would need to know the path length and the molar extinction coefficient to answer that question. If you know these, it's an extremely simple matter of Beer's Law and algebra.
