Question

Jeff's body contains about 5.12 L5.12 L of blood that has a density of 1060 kg/m3.1060 kg/m3. Approximately 45.0%45.0% (by mass) of the blood is cells and the rest is plasma. The density of blood cells is approximately 1125 kg/m3,1125 kg/m3, and about 1%1% of the cells are white blood cells, the rest being red blood cells. The red blood cells are about 7.50????m7.50μm across (modeled as spheres). What is the mass of the blood mbloodmblood in Jeff's body?

Answer 1

Answer:

5.4272 kilogram is the mass of the blood in Jeff's body.

Explanation:

Mass of the blood in Jeff's body = m

Volume of the blood in Jeff's body = V = 5.12 L

Density of blood = $1060 kg/m^3=1.060 kg/L$

$1m^3= 1000 L$

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

$D=\frac{M}{V}$

$M=D\times V$

$M=1.060 kg/L\times 5.12 L=5.4272 kg$

5.4272 kilogram is the mass of the blood in Jeff's body.
