Right! Since carbon comprises 18.5% of the body and oxygen comprises 65% of the body, in a 100 gram sample, you'd find 18.5 g of carbon and 65 g of oxygen. Good work!

Yes. Calcium, potassium, sulfur, and chlorine, along with phosphorus and sodium, are grouped in the "other" elements. Together, these six elements make up 4% of the human body.

Exactly! Although we can't tell exactly what percentage of the body is composed of iron, we can infer that iron is probably one of the 15 trace elements in the body, and therefore makes up less than 0.1%.
