Answer :
Final answer:
To calculate the molar absorptivity of 35.9 M¹ with a path length of 1.8 cm, divide the slope by the path length to get 19.9 M¹ cm¹.
Explanation:
The student has asked how to calculate the molar absorptivity (ɛ) given a slope of the calibration curve (35.9 M¹) and a path length of 1.8 cm. To find the molar absorptivity, which has units of M¹ cm¹, you'll need to adjust the given slope by the path length. Since the calibration curve slope is given as ɛb, where b is the path length (Beer-Lambert law), molar absorptivity can be calculated by dividing the slope by the path length. In this case, ɛ = 35.9 M¹ / 1.8 cm, which yields a molar absorptivity (ɛ) of 19.9 M¹ cm¹.
