When a 0.740-g sample of trinitrotoluene (TNT), C 7 H 5 N 2 O 6 , is burned in a bomb calorimeter, the temperature increases from 23.4 °C to 26.9 °C. The heat capacity of the calorimeter is 534 J/°C, and it contains 675 mL of water. How much heat was produced by the combustion of the TNT sample?

Question: I've done both of the graphs and generated an equation from excel, I just need help
explaining A-B. Below is just the information I used to get the graphs obtain the graph please help.
Prepare two graphs, the first with the percent transmission on the vertical axis and concentration on
the horizontal axis and the second with absorption on the vertical axis and concentration on the
horizontal axis.

A.) Give an equation that relates either the % transmission or the absorption to the concentration. Explain how you
arrived at your equation.
B.) What is the relationship between the percent transmission and the absorption?
C.) Determine the concentration of the ironlll) salicylate in the unknown directly from the graph and from the best fit
trend-line (least squares analysis) of the graph that yielded a straight…
