A typical adult human body contains approximately 2.500 L of blood plasma. How many grams of blood plasma are in the typical adu
Ira Lisetskai [31]

Answer:

2,575 grams of blood plasma are in the typical adult human body

Step-by-step explanation:

Density is the property that matter, whether solid, liquid or gas, has to compress into a given space, so it relates the amount of mass per unit volume. So the density of a substance is the quotient between mass and volume:

density=\frac{mass}{volume}

In this case, you know:

  • density=1.03 \frac{g}{mL}
  • mass= ?
  • volume= 2.5 L= 2,500 mL (being 1 L= 1,000 mL)

Replacing:

1.03\frac{g}{mL} =\frac{mass}{2,500 mL}

and solving, you get:

mass= 1.03 \frac{g}{mL} *2,500 mL

mass= 2,575 g

<u><em>2,575 grams of blood plasma are in the typical adult human body</em></u>

They have the same volume, so it's not a or d, but the surface area of a is 104, and the surface area of b is 94, so the answer is B.
