Document Summary
This page left blank (you can use it for scratch paper, long responses, etc) Multiple choice questions: (5 points) in the earth"s atmosphere the co2 mixing ratio is increasing at about 2 ppm/yr and the. Student id#: _____________ background co2 level is now near 400 ppm (compared to the preindustrial concentration of ~270ppm). The cost is inversely proportional to the precision. What is the least expensive instrument that will meets the measurement requirements: 10, 1, 0. 1, 0. 5, 0. 01, (10 points) a team of students attempts to quantify the amount of toxic metals in their hair. Their procedure is: weigh a lock of hair from each partner dissolve the hair in 1 ml strong acid neutralize with a strong base, followed by bringing the total volume to 10 mls. They used mp-aes to measure the concentration of zn, cu and mn in the final solution. They then express their result as moles of metal per gram of hair.
