Final answer:
In 1.0 mol of C₆H₁₂O₆, there are 6 moles of carbon atoms, 12 moles of hydrogen atoms, and 6 moles of oxygen atoms.
In 16.8 mol of H₂O, there are 33.6 moles of hydrogen atoms and 16.8 moles of oxygen atoms.
In 100.0 g of Al, there are 3.706 moles of Al.
Step-by-step explanation:
To calculate the number of moles of each type of atom in a compound, we need to look at the chemical formula of the compound. In the case of C₆H₁₂O₆, there are 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Therefore, there are 6 moles of carbon atoms, 12 moles of hydrogen atoms, and 6 moles of oxygen atoms in 1.0 mol of C₆H₁₂O₆.
Similarly, in 16.8 mol of H₂O, there are 16.8 moles of water molecules. Each water molecule contains 2 hydrogen atoms and 1 oxygen atom. Therefore, there are a total of 16.8 * 2 = 33.6 moles of hydrogen atoms and 16.8 moles of oxygen atoms in 16.8 mol of H₂O.
In 100.0 g of Al, we can use the molar mass of aluminum from the periodic table, which is 26.98 g/mol, to calculate the number of moles. Therefore, there are 100.0 / 26.98 = 3.706 moles of Al in 100.0 g of Al.
