Question

On Greg's last visit to his doctor, he complained of feeling tired. Sandra, the registered nurse, withdrew 6.5 mL of blood, which was sent to the lab and tested for iron. The normal range for serum iron in men is 80 to 160 mcg/dL. Greg's iron test showed a blood serum iron level of 39 mcg/dL, How many micrograms of iron were in the 6.5-mL sample of Greg's blood?

Answer 1

2.5 mcg of iron

Step-by-step explanation:

Density is given as;

D= m/v

Where;

m= mass

v= volume

mass= ?

volume= 6.5 ml or 0.065 dl

d= 39 mcg/dL

m= density × volume

m= 39 mcg/dL × 0.065 dl

m= 2.5 mcg of iron
