Glucose has the chemical formula `C_6H_(12)O_6` . Each molecule of glucose contains 12 hydrogen atoms, so the number of hydrogen atoms is therefore 12 times the number of molecules:
12 x (3.22 x 10^23) = 3.86 x 10^24 atoms of hydrogen
To solve this problem you need to know the chemical formula of glucose. From the formula you can see that each molecule is made up of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. To find the number of atoms of any element, multiply its subscript in the formula by the number of molecules.
Glucose is a simple sugar that's made by plants during photosynthesis and used by plants and animals for energy. Carbohydrates that are consumed by animals are broken down into molecules of glucose, which release energy through the process of cellular respiration.
