A 28.20 g galvanized steel washer with copper coating is treated with nitric acid. The copper coating is completely removed by reaction with nitric acid and the mass of the washer is now 26.52 g. The washer has an outer diameter D = 45.0 mm, an inner diameter d = 9.0 mm, and a thickness h = 3.0 mm. Copper has density of 8.96 g/cm^3.
What is the total volume of copper coating (in mm^3, 1cm^3 = 1000mm^3)?
