ANSWER:"e is a measure of the amount of light absorbed per unit concentration".
Molar absorbtivity is a constant for a particular substance, so if the concentration of the solution is halved so is the absorbance, which is exactly what you would expect.The formula for the molar absorptivity is given as followings:
A=ecl
e=A/cl
e = the molar absorptivity
where A is known as the A is known as the absorbance, l measures the length of the solution the light passes through,c is theconcentration of solution in mol /dm^3.
Remember that the absorbance of a solution will vary as the concentration or the size of the container varies. Molar absorptivity compensates for this by dividing by both the concentration and the length of the solution that the light passes through. Essentially, it works out a value for what the absorbance would be under a standard set of conditions - the light travelling 1 cm through a solution of 1 mol dm-3. a

If the temperature is 84 Fahrenheit what is the approximate temperature in degrees celsius?
To convert Fahrenheit to Celsius, you can use the formula: ( C = \frac{(F - 32) \times 5}{9} ). For 84°F, this calculation gives approximately 28.9°C. So, the temperature of 84°F is roughly 29°C.
What temp F when -7C?
To convert -7°C to Fahrenheit, you can use the formula ( F = \frac{9}{5}C + 32 ). Plugging in -7 for ( C ), the calculation is ( F = \frac{9}{5}(-7) + 32 ), which equals 19.4°F. Therefore, -7°C is approximately 19.4°F.
How much Fahrenheit is 37 Celsius?
To convert Celsius to Fahrenheit, you can use the formula: ( F = (C \times \frac{9}{5}) + 32 ). For 37 degrees Celsius, the calculation is ( (37 \times \frac{9}{5}) + 32 ), which equals 98.6 degrees Fahrenheit. Therefore, 37 Celsius is equivalent to 98.6 Fahrenheit.
What is the temperature in Fahrenheit for -20 and degC?
To convert -20 degrees Celsius to Fahrenheit, you can use the formula ( F = \frac{9}{5}C + 32 ). Plugging in -20 for ( C ), the calculation is ( F = \frac{9}{5}(-20) + 32 = -4 ) degrees Fahrenheit. Therefore, -20 degrees Celsius is equivalent to -4 degrees Fahrenheit.

How do you calculate the concentration of a solution using Beer's Law?
To calculate the concentration of a solution using Beer's Law, you can use the formula A lc, where A is the absorbance of the solution, is the molar absorptivity of the substance, l is the path length of the cuvette, and c is the concentration of the solution. By rearranging the formula, you can solve for the concentration of the solution, c A / (l).

What is the molar absorptivity of red dye?
The molar absorptivity of a substance is a measure of how strongly it absorbs light at a particular wavelength. To determine the molar absorptivity of red dye, you would need to know the specific type of red dye as well as the wavelength of light at which its absorption is being measured. Molar absorptivity is typically provided in literature or can be experimentally determined.
Why can you not measure the molar absorptivity of the food dyes?
You can.
