Question

In human females, what is the molarity of plasma based on average protein concentration? Please show how to calculate. Thanks !

Standard Blood Values for Humans Measurement Human Males Mean 5.4 45.0 16.0 7500 4800-108007000 4800-10800 Human Females Unit Mean Range 4.2-5.9 42-50 13-16 Range 4.2-5.9 40-48 12-15 RBC Hct 4.8 42.0 14.0 million cells/mm3 grams/100 ml cells/mmi micrometers3 WBC MCV MCHC Total protein concentration 87 87 34 7 80-94 33-38 6-8 80-94 33-38 34 7 6-8 grams/100ml Frequently Used Molecular Weights and Osmolarities Glucose 180 NaCl 58.5 Average Protein 69,000 Hemoglobin 68,000 Molecular Weight (g/mole) Osmoles/mole 2

Explanation / Answer

given here mean protein weight in female is 7 g per 100ml.

so in 1000ml there will be 70g of protein

molarity is the no. of moles present per litre of a solution.

given here moleular weight of protein is 69,000 g/mole

so no. of moles of protein in female per litre will be     70/69,000 = 0.00101

so molarity of protein in female will be 0.00101 (or 1.01 x 10 -3 ).
