Answer:
(4) 266 moles
Explanation:
We have Dinitrogen Pentoxide N2O5
6.41*10^25 molecules are given
No of Moles of N2O5 = 
= 
= 106.5 mol
Now using Unitary Method
2 Mole of Nitrogen pentoxide require 5 mole of Oxygen to form N2O5
1 mole of N = 
In 106.5 mole of N = 
= 266.25 mole
So, 6.41*10^25 molecules of N2O5 will require 266.25 mole of Oxygen atoms.
The density of the patient's hemoglobin in their blood in units of g/ml = 0.2g/mL
<h3>Calculation of hemoglobin density</h3>
Hemoglobin is the red blood cell pigment that transports oxygen to the body cells.
1 gram of hemoglobin = 2.15mg
Blood volume of the patient is = 4.9ml
Density= mass/volume
Therefore the density of patients hemoglobin= 1/4.9 = 0.2g/mL
