Question

A patient's blood test shows that her hemoglobin concentration is 15.0g/dL. How many milligrams of hemoglobin are in every 3.00 mL of the patient's blood?

Answer 1

450g

Step-by-step explanation:

1dL = 100ml --> Therefore 3.00ml = (3*100)dL = 300dL.

15.0g/dL indicates that there are 15g of hemoglobin in every 1dL. Previously we found that we have 300dL of patient's blood sample. Therefore the total amount of hemoglobin can be calculated as the following:

15.0g/dL * 300dL = 450g

Therefore there are 450g of hemoglobin in 3.00 ml of the patient's blood.
