1 troy ounce = 31.103 grams (http://scienceworld.wolfram.com/physics/TroyOunce.html) density of pure platinum = 21.45 grams/cm^3 (http://www.chemistry.org/portal/a/c/s/1/acsdisplay.html?DOC=sitetools\periodic_table.html#) Assuming that your actual material, which is only certified as being 99.95% pure has the density of pure platinum: volume = mass/density = [1 troy ounce * 31.103 grams/(troy ounce) ]/ [21.45 grams/cm^3] = 1.45 cm^3 = 0.088 in^3 |
