Guanosine has a maximum absorbance of 275 nm. and the path length is 1 cm. Using a spectrophotometer, you find the that . What is the concentration of guanosine?
To solve this problem, you must use Beer's Law.
0.70 = (8400 M-1 cm-1)(1 cm)( )
Next, divide both side by [(8400 M-1 cm-1)(1 cm)]c = 8.33x10-5 mol/L
