You make a solution that has 20 molecules of glucose, 210 molecules of hemoglobin, and 770 molecules of water. What is the solute concentration in %?

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%
