Concentration (M) Absorbance 0.0024 0.3 0.0036 0.5 0.0048 0.63 0.0060 0.73 0.0072 0.83 What is the value of the y-intercept on your Beer’s Law plot? Provide possible explanations why the number is not zero. The value of y-intercept: y = 0.082 The y-intercept means the value of absorbance of the solution when the concentration is equal to 0. However, because in order to create five standard solutions, we dilute from the stock solution. The concentration can be really small but it is not going to be zero.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
