molar mass - Swedish translation – Linguee

Molförhållandet in English with contextual examples

One mole of H 2 O is made up of 2 moles of hydrogen atoms and 1 mole of oxygen atom. Molar mass of atoms. Mass of 1 mole of Hydrogen atoms= 1 g /mol. Mass of 1mole of Oxygen atoms = 16 g/mol. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol.

Molar mass of water

Therefore, Molar mass of water would be: 2 x H + O = 2 x 1.008 + 16 = 18.016 g/mol = 18 g/mol. Molar mass equation: Water may have a molar mass of 18.02 g/mol, but individual water molecules can have a weight that ranges from 18.011 Da to 22.028 Da, due to the presence of different isotopes of hydrogen and oxygen. The molar mass can then be seen as a measure of the average molecular masses of the individual molecules in one mole of a substance. The molar heat of vaporization for water is 40.7 kJ/mol. To get the heat of vaporization, you simply divide the molar heat by 18.015 g/mol.
