Question

Hemoglobin is an oxygen-carrying protein found in blood. The average concentration of hemoglobin in blood is 15.0 g hemoglobin/dl blood in men and is 8.5 g hemoglobin/dl blood in women. If a woman loses 11.0 ml of blood, how many grams of hemoglobin did the woman lose?

Answer 1

A woman with a hemoglobin concentration of 8.5 g/dl in her blood would lose 0.935 grams of hemoglobin if she lost 11.0 ml of blood.

Step-by-step explanation:

Hemoglobin is a protein in red blood cells responsible for carrying oxygen. To calculate the amount of hemoglobin lost with 11.0 ml of blood, we use the concentration of hemoglobin in women, which is 8.5 g/dl. Since 1 dl is equivalent to 100 ml, we first convert 11.0 ml to dl, which is 0.11 dl. Multiplying the concentration of hemoglobin by the volume of blood lost gives us the amount of hemoglobin lost: 8.5 g/dl * 0.11 dl = 0.935 g.

Therefore, the woman lost 0.935 grams of hemoglobin when she lost 11.0 ml of blood.

Answer 2

The woman lost approximately 0.935 grams of hemoglobin when she lost 11.0 ml of blood, using the average concentration of hemoglobin in blood for women.

Step-by-step explanation:

To calculate the amount of hemoglobin lost by the woman, we use the average concentration of hemoglobin in blood for women, which is 8.5 g hemoglobin/dl blood. We know that the woman lost 11.0 ml of blood. Since there are 100 ml in a deciliter (dl), the volume of blood lost in deciliters is 11.0 ml × (1 dl / 100 ml) = 0.11 dl.

Using the concentration of hemoglobin, the calculation for the total grams of hemoglobin lost is:

8.5 g/dl × 0.11 dl = 0.935 g

Therefore, the woman lost approximately 0.935 grams of hemoglobin when she lost 11.0 ml of blood.
