A 200 mL cup of water contains approximately 11.1 moles of water, since 1 mole of water (H₂O) is about 18 grams and 200 mL of water weighs roughly 200 grams. Given that one mole contains approximately (6.022 \times 10^{23}) molecules, this results in about (6.7 \times 10^{24}) water molecules. Since each water molecule consists of three atoms (two hydrogen and one oxygen), the total number of atoms in a 200 mL cup of water is around (2.0 \times 10^{25}) atoms.
