1. A soln containing iodide ion has a percent transmittance reading of 72.3% What is the molarity of the iodide ion in this soln?
2. A soln was made by dissolving 5 g of sodium iodide in enough water to make 500mL of soln. What is the expected percent transmittance for this soln?
3. Soln "A" contians the iodide ion and a percent T reading of 55.5%. Soln "B" contains iodide ion and has a percent T reading of 77.7%. If 50mL of soln "A" is mixed with 100mL of soln "B" what will be the percent T reading?
