Question

A typical adult body contains 6.0 L of blood. The hemoglobin content of blood is about 15.5 g/100.0 mL of blood. The approximate molar mass of hemoglobin is 64,500 g/mol. How many moles of hemoglobin are present in a typical adult?

Answer 1

Answer and Explanation:

To calculate the number of moles of hemoglobin present in a typical adult, we can use the given information and the formula for calculating the number of moles (n) as n = mass / molar mass.

First, we can calculate the total mass of hemoglobin in a typical adult body: 6.0 L blood * (1000 mL / 1 L) * (15.5 g hemoglobin / 100 mL blood) = 930 g hemoglobin

Next, we can use the molar mass of hemoglobin to calculate the number of moles: n = 930 g / 64,500 g/mol = 0.0144 mol

So, a typical adult body contains approximately 0.0144 moles of hemoglobin.
