"How many atoms are in 1.00 mol of H_(2)O Answer: 1.81times 10^24atoms

2. The number of molecules in 10.0 moles of Carbon dioxide can be calculated using Avogadro's number, which is molecules/mol. Therefore, the number of molecules in 10.0 moles of Carbon dioxide is molecules.3. The number of formula units in 0.670 moles of Iron (II) oxide can be calculated using Avogadro's number, which is formula units/mol. Therefore, the number of formula units in 0.670 moles of Iron (II) oxide is formula units.4. The number of molecules in 0.63 moles of Nitrogen monoxide can be calculated using Avogadro's number, which is molecules/mol. Therefore, the number of molecules in 0.63 moles of Nitrogen monoxide is molecules.5. The number of moles in Magnesium atoms can be calculated using Avogadro's number, which is atoms/mol. Therefore, the number of moles in Magnesium atoms is moles.6. The number of moles in Sulfur atoms can be calculated using Avogadro's number, which is atoms/mol. Therefore, the number of moles in Sulfur atoms is moles.7. The number of atoms in 1.00 mol of can be calculated by multiplying the number of molecules in 1.00 mol of by the number of atoms per molecule of . Since there are 3 atoms in each molecule of , the number of atoms in 1.00 mol of is atoms.
