The Importance of Glucose in the Human Body
Glucose is an essential molecule that is involved in numerous biological processes. It is a primary source of energy for cells, and its metabolism is crucial for maintaining proper bodily functions. The human body obtains glucose from the food we consume, and it is then broken down into energy through a process called cellular respiration.
Calculating the Mass Percentage of Carbon in Glucose
To calculate the mass percentage of carbon in glucose, we need to use the periodic table to determine the atomic masses of carbon, hydrogen, and oxygen. The atomic masses of these elements are:
- Carbon (C): 12.01 g/mol
- Hydrogen (H): 1.01 g/mol
- Oxygen (O): 16.00 g/mol
The molecular formula of glucose is . To calculate the mass percentage of carbon, we need to calculate the total mass of carbon in one molecule of glucose and then divide it by the total molecular mass of glucose.
Step 1: Calculate the Total Mass of Carbon in Glucose
The molecular formula of glucose indicates that there are 6 carbon atoms in one molecule. To calculate the total mass of carbon in glucose, we multiply the atomic mass of carbon by the number of carbon atoms:
6 x 12.01 g/mol = 72.06 g/mol
Step 2: Calculate the Total Molecular Mass of Glucose
To calculate the total molecular mass of glucose, we need to add the masses of all the atoms in the molecule. The molecular formula of glucose is , which means there are 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. We can calculate the total molecular mass as follows:
Total molecular mass = (6 x 12.01 g/mol) + (12 x 1.01 g/mol) + (6 x 16.00 g/mol) Total molecular mass = 72.06 g/mol + 12.12 g/mol + 96.00 g/mol Total molecular mass = 180.18 g/mol
Step 3: Calculate the Mass Percentage of Carbon in Glucose
To calculate the mass percentage of carbon in glucose, we divide the total mass of carbon by the total molecular mass of glucose and multiply by 100:
Mass percentage of carbon = (72.06 g/mol / 180.18 g/mol) x 100 Mass percentage of carbon = 40.0%
Conclusion
In conclusion, the mass percentage of carbon in glucose is 40.0%. This calculation is essential in understanding the composition of glucose and its role in various biological processes. The periodic table provides a valuable tool for calculating the mass percentage of elements in molecules, and it is a fundamental concept in chemistry.
