Answer:
Percentage of water = 2%
Percentage of water = 21%
Percentage of water = 77%
Explanation:
Given data:
Number of molecules of glucose = 20
Number of molecules of hemoglobin = 210
Number of molecules of water = 770
Solution:
To calculate the percentage 1st of all we will determine the total number of molecules.
Total number of molecules = Number of molecules of water + hemoglobin + glucose
Total number of molecules = 770 + 210 + 20
Total number of molecules = 1000
Percentage of water:
Percentage of water = 770/1000 ×100
Percentage of water = 0.77 ×100
Percentage of water = 77%
Percentage of hemoglobin:
Percentage of water = 210/1000 ×100
Percentage of water = 0.21 ×100
Percentage of water = 21%
Percentage of hemoglobin:
Percentage of water = 20/1000 ×100
Percentage of water = 0.02 ×100
Percentage of water = 2%
