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 0.20g/cm^3, and its surface area is 1242m^2 per gram of material. 1. Calculate the volume of a 35.0mg sample of this material. 2. Calculate the surface area for a 35.0mg sample of this material. 3. A 10.0-mL sample of contaminated water had 7.748mg of mercury in it. After treatment with 10.0mg of the new spongy material, 0.001mg of mercury remained in the contaminated water. What percentage of the mercury was removed from the water? 4. What is the final mass of the spongy material after the exposure to mercury?
