How many molecules of water,H₂O,comprise 3.64 grams?

Question

Quizplus · Accepted Answer

To find the number of water molecules in 3.64 grams, first calculate the molar mass of water (H2O): (2*1.01) + 16.00 = 18.02 g/mol. Then, use the formula: number of moles = mass / molar mass = 3.64 g / 18.02 g/mol ≈ 0.202 moles. The number of molecules is found by multiplying the number of moles by Avogadro's number (6.022 × 10^23 molecules/mol): 0.202 moles * 6.022 × 10^23 molecules/mol ≈ 1.22 × 10^23 molecules.
