Absorbance measurements are made on two copper (II) sulfate solutions. One is 0.20 molar and the other is 0.40 molar. The measurements are made using identical path lengths. Which solution will absorb less light? Explain your answer. 0.20 M because its lower concentration results in more light being transmitted. 0.40 M because its higher concentration results in more light being transmitted. O 0.40 M because its higher concentration results in less light being transmitted. O 0.20 M because its lower concentration results in less light being transmitted.

6.72 LED bulbs offer a fairly new lighting alternative, and are becoming increasingly popular in home lighting. These bulbs combine excellent energy efficiency with the “warm” light and dimming ability of incandescent lights. Although LED bulbs are expensive, manufacturers claim that subsequent savings will more than offset the initial costs. Analyze the relative cost of incandescent versus LED lighting, assuming that the information in the table below is accurate. Are industry claims of cost savings justified? LED Incandescent Initial cost $4.00 $0.75 Electricity usage 8 watts 60 watts Electricity cost $0.04/kwh $0.04/kwh Lifetime 25,000 hours 1,500 hours
