Mass is the product of density and volume.
\n" ); document.write( "Convert mm to m to be consistent in units.
\n" ); document.write( "The volume of a sphere is,
\n" ); document.write( "\"V=%284%2F3%29%2Api%2A%28D%2F2%29%5E3=%28pi%2F6%29%2825%2F1000%29%5E3\"
\n" ); document.write( "\"V=6.54x10%5E%28-5%29\"\"m%5E3\"
\n" ); document.write( "Then
\n" ); document.write( "\"m=rho%2AV=250%2A6.54x10%5E%28-5%29\"
\n" ); document.write( "\"m=0.01636\"kg
\n" ); document.write( "\"highlight%28m=16.4%29\"grams
\n" ); document.write( "Then use a conversion of 454 grams=16 ounces
\n" ); document.write( "\"m=16.4%2816%2F454%29\"
\n" ); document.write( "\"m=0.58\"ounces
