What Is The Mass Of $9.024 \times 10^{23}$ Glucose \left( C_6 H_{12} O_6 \right ] Molecules?
Introduction
In chemistry, understanding the mass of molecules is crucial for various calculations and applications. The mass of a molecule can be calculated using its molecular formula and the atomic masses of its constituent elements. In this article, we will calculate the mass of $9.024 \times 10^{23}$ glucose molecules using their molecular formula and atomic masses.
Understanding the Molecular Formula
The molecular formula of glucose is $C_6 H_{12} O_6$. This formula indicates that one molecule of glucose consists of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.
Atomic Masses of Elements
The atomic masses of the elements involved in the glucose molecule are:
- Carbon (C): 12.01 g/mol
- Hydrogen (H): 1.008 g/mol
- Oxygen (O): 16.00 g/mol
Calculating the Mass of a Single Glucose Molecule
To calculate the mass of a single glucose molecule, we need to multiply the atomic masses of its constituent elements by their respective numbers in the molecular formula.
Mass of a single glucose molecule = (6 x 12.01 g/mol) + (12 x 1.008 g/mol) + (6 x 16.00 g/mol) = 72.06 g/mol + 12.096 g/mol + 96.00 g/mol = 180.156 g/mol
Calculating the Mass of $9.024 \times 10^{23}$ Glucose Molecules
Now that we have the mass of a single glucose molecule, we can calculate the mass of $9.024 \times 10^{23}$ glucose molecules by multiplying the mass of a single molecule by the number of molecules.
Mass of $9.024 \times 10^{23}$ glucose molecules = 180.156 g/mol x $9.024 \times 10^{23}$ = 1.629 x $10^{26}$ g
Conclusion
In conclusion, the mass of $9.024 \times 10^{23}$ glucose molecules is approximately 1.629 x $10^{26}$ g. This calculation demonstrates the importance of understanding the molecular formula and atomic masses of elements in chemistry.
