Is it true the soul weighs 3 grams?

Question

Isnt it logical? When you die you loose 3 grams, and people say its the soul, whats up?

Answer 1

It's 21 grams.

Answer 2

that's easy to burn off...lol

Answer 3

Yes it is true that when someone dies they weighs less than when he/she were alive but to say someone has found a way to tell the weight of the soul, is somewhat difficult to believe.  

Answer 4

No there is no such thing as a soul.  When you die you lose some weight because the air in your lungs escapes.  Air has mass too.

Answer 5

Is that what happens when it gets stuck between a rock & a hard place?
