Answer:
The blood will contain 750 grams of O2
Explanation:
Volume of blood in the human body = 15 deciliters
Mass of hemoglobin per deciliter of blood = 15 grams
Mass of hemoglobin in 50 deciliters of blood = 50×15 = 750 grams
Since all the hemoglobin molecules are saturated with O2, mass of O2 in the blood will be the same as mass of hemoglobin molecules in the blood.
Therefore, mass of O2 in the blood is 750 grams
An adaption is a change or process an organism goes through to become better suited for its environment.
Example: A polar bear having white fur in order to blend in in its environment.
The question in English is "<span>Determine the mass, in kg, of a material that is contained in a volume of 18L. It is known that the material density is 0.9 g/cm 3"
Answer:
</span>
We can use a simple
equation to solve this problem. <span>
d =
m/v</span><span>
<span>Where </span>d <span>is
the density, </span>m <span>is
the mass and </span>v is the volume.
d = </span>0.9<span> g/cm³
m = ?
v = </span>18 L = 18 x 10³ cm³<span>
By applying the equation,
<span> 0.9 g/cm³ = m / </span></span>18 x 10³ cm³<span>
m = 0.9 g/cm³ x </span>18 x 10³ cm³<span>
<span>
</span>m = 16200 g
m = 16.2 kg
Hence, the mass of
18 L of material is 16.2 kg.</span>
