'Yes' if you use your figure for density of 17 gm/cubic cm (which is wrong) , but 'no' if you use the correct density of Gold of 19.320 gm/cu.cm(see http://hypertextbook.com/facts/2004/RuwanMeepagala.shtml)(For gold nuggets, try the specific gravity test on this site:www.gold-nuggets.org/specific-gravity-test.htm)Now, your ball is not a nugget, but it can be worked out as follows:-Volume of sphere of golden ball= 4/3 x pi x radius cubed = 4/3 x 3.142 x 7.5 x 7.5 x7.5 =1767.375 cu. cm Density of Gold = 19.320 gm/cu. cm Therefore, Mass of golden ball if made of pure gold=1767.375 x 19.320 =34145.685 gm =34.146kg However, the mass of the actual ball is 30.026kg This means the ball is not pure gold, but an alloy (probably copper).Percentage of gold in ball =(30.026 / 34.146) x 100/1 =87.93% As pure gold is 24 carat , this works out to 21 carats. Summary:-This ball is not pure gold, but an alloy (probably copper) of 21 carats.
