How many water molecules are there in 36. g of water? Express your answer as a multiple of Avogadro's number NA. (The molecular structure of a water molecule is H₂O.) A) 0.020 N_A B) 18. N_A C) 36. N_A D) 2.0 N_A E) 3.0 N_A

Question

Quizplus · Accepted Answer

The molar mass of water (H2O) is approximately 18 g/mol, meaning 36 g of water is equivalent to 2 moles. Since Avogadro's number (NA) represents the number of particles in one mole of a substance, 36 g of water contains 2 NA molecules.
