What is the atomic mass of 5 water molecules?

The Atomic Mass of a single water molecule (H₂O) is approximately 18.02 grams per mole, calculated from the atomic masses of hydrogen (about 1.01 g/mol) and oxygen (about 16.00 g/mol). Therefore, the total mass of 5 water molecules can be calculated by multiplying the mass of one water molecule by 5, resulting in about 90.1 grams per mole for 5 molecules. However, since the atomic mass is typically expressed per mole, the mass of 5 water molecules in grams would be significantly less than this value.
