Question

The human body is 0.0040% iron. How many milligrams of iron does a 165 pound person contain?​

Answer 1

in a body of 165 pounds, the iron content is 2993.707 mg

Step-by-step 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
