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 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.
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.
What information is needed to determine molecular formula?
the empirical formula and the molar mass
How do you calculate 1mM?
To calculate 1 millimolar (mM) concentration of a substance, you need to know the molar mass of the substance. Then, divide 1 millimole (mmol) by the molar mass to obtain the volume of the substance needed to make a 1 mM solution.
The number of moles of oxygen in the reaction vessel is?
To calculate the number of moles of oxygen in the reaction vessel, you need to know the amount of oxygen in grams and its molar mass. Then divide the mass of oxygen by its molar mass to obtain the number of moles. The formula to calculate the number of moles is: moles = mass / molar mass.

What is the molar extinction coefficient of Phenol red at 610NM?
Molar extinction coefficient of phenol ret at 610nM is 22 mM-1 cm-1
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 is the extinction coefficient (aka molar absorptivity) for CuSO4 at the wavelength you used?
The extinction coefficient, also known as molar absorptivity, for CuSO4 at the specific wavelength used is a measure of how strongly the compound absorbs light at that wavelength. It is a constant value that helps determine the concentration of the compound in a solution based on its absorbance.
What is the extinction coefficient (aka molar absorptivity) of CuSO4 at the wavelength you used?
The extinction coefficient, also known as molar absorptivity, of CuSO4 at the specific wavelength used is a measure of how strongly the compound absorbs light at that wavelength. It is a constant value that helps determine the concentration of the compound in a solution based on its absorbance.
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.

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.
How is the number of moles of an element determined from known mass?
The molar mass is the measurement of mass per one mole of a substance. If the mass of a matter is known, divide it from the molar mass to obtain the number of moles.
