Question

Samantha weights 55kg. If 7% of Samantha’s weight is blood, what is her blood volume ?

Answer 1

To find Samantha's blood volume, we need to first calculate the amount of blood she has in her body based on her weight.

We know that 7% of Samantha's weight is blood, so we can calculate this as:

0.07 x 55kg = 3.85kg

This means that Samantha has 3.85kg of blood in her body. However, we typically measure blood volume in liters, so we need to convert kilograms to liters.

The density of blood is about 1.06 kg/L, so we can convert Samantha's blood weight to blood volume as follows:

3.85kg ÷ 1.06 kg/L ≈ 3.63 L

Answer 2

3.85 kg

Explanation:

Samantha's blood volume is 55 * 0.07 = 3.85 kg.

Blood volume is the total amount of blood in the body. It is calculated by multiplying the weight of the person by the percentage of their weight that is blood.
