SPE501 Case Study Reading Fluency

please please answer super fast i need it before 9:30pm please answer all

Which of the five dyes tested in this experiment has the strongest ability to absorb light? How do you know?

If a solution has an absorbance of 2 you can be certain that  the solution is highly diluted and needs to be concentrated  all the statements are correct  this is a reliable absorbance and downstream analysis can be done  the solution is highly concentrated and needs dilution

I really need help analyzing and interpreting these spectra to find a chemical formula and compound structure!

If the concentration of a food coloring solution is increased by a factor of 3, how will the absorbance change?

Why were the absorbance measurements recorded at lambda max (504 nm)?   Question 1 options:   at lambda max impurities in the sample do not absorb any light   Because the allura red dye absorbs red color at 504 nm   at lambda max the absorbance is the most sensitive to dye concentration   at lambda max the absorbance is the least sensitive to dye concentration

what is the reading of this buret?

I have 4 Questuion    Q1: find the A , T , T% of a 2.4X10-3 mol L-1 solution of a substance whose molar absorptivity is 313 L M-1 cm -1 at 520 nm when measured in a cell of 2.00 cm pathlength ؟   Q2: A sample in a 1 cm cuvette transmits 79% of light at 280 nm , what is the absorbance ? if the molar extinction coefficient is 2.0 M-1 cm-1 , what is the concentration of the sample ? Q3 : the aspirin an analgesic form complex with metal ion which has a molar absorpitvity of 8000 L M-1 cm-1 at ( lenada max 435 nm ) . calculate the absorbance of 6.77 X 10-5 M solution of the complex measured in a 1.00 cm cell at 435 nm ? Q4 :Find the A and T% of a 6.5X10-4 Mol L-1 solution of a drug ( molecular weigth 200 ) whose absorpitvity is 0.026 L cm-1 g-1 at 520 nm when measured in a cell of 2.00 cm pathlength ?

Guanosine has a maximum absorbance of 275 nm. ϵ275=8400M−1cm−1, and the path length is 1 cm. Using a spectrophotometer, you find that A275=70. What is the concentration of guanosine?

Using the graph below, what does the R2 value tell us about the data? Absorbance versus Concentration 1 y = 29894x - 0.0169 R² = 0.9994 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0.00E+00 5.00E-06 1.00E-05 1.50E-05 2.00E-05 2.50E-05 3.00E-05 3.50E-05 Concentration (M) The data is precise. The data is accurate. The data is precise but inaccurate. The data fits the curve well. The data is precise and accurate. Absorbance (AU) O O

3. Find the position of the absorption peak of a low-resolution spectrum of 12C180

What region of the spectrum is represented here?   if the concentration of the substance measured was 0.50 M, how would the spectrum change if the concentration were changed to 1.0 M? Or, would it stay the same?  Explain

please can you please im begging can you please create graphs with Excel (or a similar program). Plot absorbance (v-axis) vs. A (×- axis) for the absorbance curve determined in part 2. Connect the points with a smooth curve. Plot absorbance (y-axis) vs. concentration (x-axis) for the Beer's Law data from part 3. Draw a best-fit line or use a program such as Excel and do a least-squares fit to determine the best-fit line through the points. please answer super super fast please please need it now its urgent just creat the graphs
