Answer:
Explanation:
Interesting question - especially if you are afflicted by something like Leukemia where it pays to know everything you can about Hemoglobin.
Molecules
1 mole of anything has 6.02 * 10^23 in this case molecules
6.4*10^-3 moles has x number of molecules
Set up the proportion
1/6.4*10^-3 = 6.02 * 10^23 molecule / x Cross Multiply
x = 6.4*10^-3 * 6.02 * 10^23
x = 3.853*10^21 molecules
Mass Hemoglobin
1 mol of hemoglobin is 64456 grams
6.4*10^-3 moles = x grams Cross multiply
x = 64456 * 6.4*10^-3
x = 412.5 grams of hemoglobin in this woman's body.
If you are American and think in pounds, then this is roughly a pound of hemoglobin.
Considering that you need hemoglobin to carry oxygen around to various organs, it is not an awful lot. That's the miracle of the human body.
