Mass of 1 water molecule
The molar mass of water is 2×1.008 + 15.994 = 18.01 g/mol. Each mole of water contains 6.022×10 23 water molecules. So, the mass of a single water molecule is the molar mass (18.01 g/mol) divided by Avogadro’s number (6.022×10 23 molecules/mole). mass of individual water molecule = 18.01 g/mol ÷ 6.022×10 23 molecules/mol = 2. ... WebFor example, water has a relative molecular mass of 18.0153 (3), but individual water molecules have molecular masses which range between 18.010 564 6863 (15) Da ( 1 …

Web22 de jul. de 2024 · So one mole of water (6.022 x 10 23 molecules) has a mass of 18.02 g. One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g. What is the mass of a water molecule in gram? 18 g/ molWater consists of one oxygen atom and two hydrogen atoms. This means that the mass of a water molecule is 1g + 1g + 16g = 18 g/ mol. WebThe mass of a single water molecule is 2.9907x10-23 g to five significant figures, or 2.9907 times one hundredth of a millionth of a millionth of a nanogram, which is itself one billionth of a gram. This of course cannot be directly measured; we instead have to indirectly measure the mass of one molecule.
