9/16. I should have done better. I was trained as a chemist!

Paul Nicholson,
Check your science books.
The human body is:
Oxygen: 65%
Carbon: 18.5%
Hydrogen: 9.5%
Nitrogen: 3.3%
The balance is various non-trace elements, including calcium, iron, phosphorus, potassium, sulfer, magnesium, chlorine, iodine, sodium, and about 12 other trace elements.

10 / 16. Well done! Mendeleev would be proud. Not as proud as last time because I scored one less!

Perk, same for me, I managed to get 10 and some were guesses; but these are not what one learns in Chem classes.
