To determine the atomic mass of glucose (C5H12O6), we need to calculate the sum of the atomic masses of all the atoms in its chemical formula.
The atomic masses of the elements can be obtained from the periodic table. For carbon (C), hydrogen (H), and oxygen (O), the atomic masses are approximately:
Carbon (C): 12.01 amu Hydrogen (H): 1.01 amu Oxygen (O): 16.00 amu
Now, let's calculate the atomic mass of glucose:
Atomic mass of C5H12O6 = (5 * Atomic mass of C) + (12 * Atomic mass of H) + (6 * Atomic mass of O) = (5 * 12.01 amu) + (12 * 1.01 amu) + (6 * 16.00 amu) = 60.05 amu + 12.12 amu + 96.00 amu = 168.17 amu
Therefore, the atomic mass of glucose (C5H12O6) is approximately 168.17 amu.
