The Attempt at a Solution
So I was wondering on how to set up the equations now, since I don't have much information? Which equations should i use to solve the problem?
Dousin12 said:I still have really difficult! To understand why you add these values!
Spectrophotometry is a technique used in chemistry to measure the amount of light absorbed by a substance. It is often used to determine the concentration of a particular chemical in a solution.
A spectrophotometer works by shining a beam of light through a sample and measuring the amount of light that passes through it. The amount of light absorbed by the sample is then compared to a reference solution to determine the concentration of the chemical of interest.
The Beer-Lambert Law is a mathematical relationship that describes the correlation between the concentration of a substance in a solution and the amount of light absorbed by that solution. It is important in spectrophotometry because it allows for the accurate determination of concentrations in a sample.
One common source of error in spectrophotometry is the presence of impurities in the sample, which can affect the accuracy of the measurements. Other sources of error include incorrect calibration of the instrument, air bubbles in the sample, and variations in the light source.
Spectrophotometry has a wide range of applications in chemistry, including determining the concentration of a substance in a solution, studying the kinetics of a reaction, and identifying unknown substances. It is also used in various industries such as pharmaceuticals, environmental monitoring, and food and beverage testing.
