A Repost of a LJ Post from a while ago

In sophomore year of college, we were doing mass balances, and it was taught that water and carbon on Earth are essentially a free flowing substances in a well mixed container. As extra credit, the professor inquired how many carbon molecules in our bodies actually were also in
Sir Issac Newton, and he provided rough numbers for us to estimate with. Later that day, I realized the that the Eucharist actually contains a significant quantity of the blood and body of Christ! However, it was not until Wikipedia arrived that I was able to gather up the data to actually find out how many molecules of Jesus' blood one consumes in a sip of wine.

Here are my assumptions and constants:

1) Humans (and Jesus) needs to produce 0.5 cc of urine per kilogram per hour to avoid renal failure
2) All of this urine was produced by ultrafiltration of His blood
3) 0.5 cc urine contains approximately 0.5 g H2O
4) The hydrosphere of the Earth Contains 1.4 E +21 kg H2O
5) A sip of wine contains 50g of H2O
6) A mole of H2O weighs 18.02 g
7) Jesus lived 36 years
8) Over 2007 Years, the blood and urine of Jesus has become well mixed with the rest of the world's water
9) This water was incorporated into the grapes that made the wine for the Eucharist
10) Jesus weighed 70 kg

Plugging in these numbers, I found out that about 13 billion molecules out of every 50 grams of water was peed out by Jesus, and therefore presumably was part of his blood. Once I figure out how much the body of Christ
weighs, I will try that calculation as well.
