no im sorry, i tried to look it up on google and nothing, im assuming since you have 206 bones in your body you could divide that by the weight of all your bones so you would divide 12 i guess, adn u can find out how much your ones weigh its about 20 % of your actualy weight I THINK, im not sure but i hope this helps.
if i am correct
heart-255 to 312 grams
intestine-they weigh however much you weigh divided by four
I realise there are more internal organs but these are all i know of at the moment. Hope this helps.
on the average, the mass of a liver is 3 lbs,
kidneys weight 150 grams each,
right lung weighs 360-560 grams, left lung weighs 330-500 grams,
brain weighs 1,300 - 1,500 grams
pancreas is 60 - 100 grams
rib bones :S ? do u know that one 2 ;P
