Answer:
in a body of 165 pounds, the iron content is 2993.707 mg
Explanation:
- % iron = 0.0040% = (mass iron / mass human) * 100
⇒ mass iron / mass human = 4 E-5
∴ mass human = 165 pounds
⇒ mass iron = 165 pounds * 4 E-5
⇒ mass iron = 6.6 E-3 pounds * ( 453.592 g/pound ) * ( 1000 mg/g )
⇒ mass iron = 2993.707 mg iron
