1. In 2009 a team from Northwestern University and Western Washington University reported the preparation of a new "spongy" material composed of Nickel, molybdenum, and sulfur that excels at removing mercury from water. The density of this new material is 0.20 g/ cm3 and its surface area is 1242 m2 per gram of substance.
a. Calculate the volume of a 10.0 mg sample of this material.
b. Calculate the surface area for this 10.0 mg sample.
c. A 10.0 mL sample of contaminated water had 7.748 mg of mercury in it. After treatment with 10.0 mg of the new material, 0.001 mg of mercury remained in the water. What percentage of the mercury was removed from the water?
