We're being asked to calculate the volume of a material with a mass of 35.0 mg and a density of 0.20 g/cm3.
We can calculate the volume of the material by using its mass and density:
mass (density) → volume
Mass = 35.0 mg
Density = 0.20 g/cm3
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 material.
Calculate the volume of a 35.0 -mg sample of this material.
