Question

What is the mass in grams of 85.32 mL of blood plasma with a density of 1.03 g/mL?

Answer 1

The mass of 85.32 mL of blood plasma with a density of 1.03 g/mL is 87.88 grams.

Step-by-step explanation:

To find the mass in grams of 85.32 mL of blood plasma with a density of 1.03 g/mL, we use the formula:

Mass = Density × Volume

Substituting the given values:

Mass = 1.03 g/mL × 85.32 mL

Before calculating, let's consider the units. Since the density is given in grams per milliliter (g/mL) and the volume is given in milliliters (mL), multiplying these together will give us grams, which is the unit we want for mass.

Now, let's do the calculation:

Mass = 1.03 × 85.32

Mass = 87.8796 g

So, the mass of the blood plasma is 87.88 grams (rounded to two decimal places).

Answer 2

Answer: The mass of blood plasma is 87.9 grams.

Explanation:

Density is defined as the mass contained per unit volume.

`Density=(mass)/(Volume)`

Given : Mass of blood plasma = ?

Density of blood plasma =
`1.03g/ml`

Volume of blood plasma =
`85.32ml`

Putting in the values we get:

`1.03g/ml=(Mass)/(85.32ml)`

`Mass= 87.9g`

Thus the mass of blood plasma is 87.9 grams.
