Explanation:
Detailed explanation-1: -Glucose has a chemical formula of: C6H12O6 That means glucose is made of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms.
Detailed explanation-2: -∙ So, total number of atoms = 6 + 12 + 6 = 24. Was this answer helpful?
Detailed explanation-3: -67×12. 046×1023=6. 023×1023=8. 0×1023 hydrogen atoms.
Detailed explanation-4: -Detailed Solution There are 12 atoms of hydrogen per molecule of glucose, which has a molecular mass of 180g/mol. Hence, the number moles of hydrogen = 12 x 1.50 = 0.10 mol. Hence, the number of hydrogen atoms is found by multiplying this by the Avogadro Constant, 6.02 x 1023. This will give 6.02 × 1022.
