Question
How much iron is there in the hemoglobin of a 70 -kg adult? Assume that the blood volume is $70 \mathrm{ml}$ $\mathrm{kg}^{-1}$ of body weight and that the hemoglobin content of blood is $0.16 \mathrm{g} \mathrm{ml}^{-1}$.
Step 1
Given that the blood volume is $70 \mathrm{ml}$ per kg of body weight, and the adult weighs 70 kg, the total blood volume is: \[ \text{Total blood volume} = 70 \mathrm{ml/kg} \times 70 \mathrm{kg} = 4900 \mathrm{ml} \] Show more…

How much iron is there in the hemoglobin of a 70 -kg adult? Assume that the blood volume is $70 \mathrm{ml}$ $\mathrm{kg}^{-1}$ of body weight and that the hemoglobin content of blood is $0.16 \mathrm{g} \mathrm{ml}^{-1}$
Iron content. How much iron is there in the hemoglobin of a $70-\mathrm{kg}$ adult? Assume that the blood volume is $70 \mathrm{ml}$ $\mathrm{kg}^{-1}$ of body weight and that the hemoglobin content of blood is $0.16 \mathrm{g} \mathrm{ml}^{-1}.$
If the hemoglobin content of serum is 0.160 g/mL, and there is about 70.0 mL of blood per kg of body weight, how much iron would there be in a 3.76 kg infant? (Hint: This is stoichiometry. You may need to look up some values...)
