a. Write an equality and two conversion factors for Greg's serum iron level.

b. How many micrograms of iron were in the 8.0-ml Sample of Greg's blood?

Short Answer

Expert verified

a. 42mcgofiron=1dLofblood

b. 3.4mcgofiron

Step by step solution

01

Part (a) Given Information

To write two conversion factors.

02

Part (a) Explanation

Micro and milli are used to measure smaller units.

Greg's iron test showed a blood serum iron level of 42mcg/dL.

The unit conversion method that is used for Greg's serum iron level is:

42mcgofiron=1dLofblood42mcgofiron1dLofbloodand1dLofblood42mcgofiron

03

Part (b) Given Information

The volume of Greg's blood sample=8.0 mL

The density of the sample is 42 mcg/dL.

04

part (b) Explanation

Unit conversion for mL into dL:

1dL=100mLor1mL=110dL=0.1dL

The calculation for mass:

Massofiron=Volumeofsample×DensityMassofiron=0.08dL×42mcg/dLMassofiron=3.4mcg

Thus, the mass of iron in the sample is 3.4 mcg.
