Q5: A spectrophotometer measures the concentration of a sample dissolved in water by shining a light through it and recording the amount of light that emerges. In other words, if we know the amount of light that is absorbed, we can calculate the concentration of the sample. For a certain substance the concentration (in moles per litre) is found by using the formula: |C=-2500 1n() Where the lo is the intensity of the incident light and I is the intensity of light that emerges. Find the concentration of the substance if the intensity I is 70% of Io. Use an appropriate standard engineering software such as MATLAB, CAS calculator, programmable calculator, Excel software, to solve and analyse this program mathematically.
