Answer:
C6H12O6
Explanation:
The 3D molecule of glucose is shown below. The α and β structure differ only by the position of the hydroxyl (OH) that is closest to the methyl (CH3) that is attached to the ring. Thus, the molecular formula is the same for both structures.
In the figure, the grey balls are the atoms of carbon, the red balls are the atoms of oxygen, and the white balls are the atoms of hydrogen. The molecular formula is determined by putting the atoms and their quantities. There are 6 carbons, 12 hydrogens, and 6 oxygens, so:
C6H12O6
