How many micrograms of iron were in the 8.0 ml sample of greg's blood? given: 42 mcg of iron per 1 deciliter of blood. write the steps to your conversions.

Answer is: there is 3,36 micrograms of iron in sample of Greg's blood.
m(Fe) = 42 mcg(micrograms).
V(Fe) = 1 dL = 1 dL · 100 mL/1dL.
V(Fe) = 100 mL.
Make proportion: m(Fe) : 8 mL = 42 mcg : 100 mL.
100 mL · m(Fe) = 8 mL · 42 mcg.
m(Fe) = 336 mL·mcg ÷ 100 mL.
m(Fe) = 3,36 mcg.
