For example, the molar mass of water (H₂O) is approximately 1 × 2 + 16 = 18 g/mol. Molecular Mass Molecular mass (older name molecular weight) is the mass of a molecule calculated as the sum of the mass of each atom in the molecule multiplied by the number of atoms of that element in the molecule.

The molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing

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. See Example #3 below. Molar heat values can be looked up in reference books. The molar heat of vaporization equation looks like this: q = (ΔH vap) (mass/molar mass) The meanings are as follows:

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 mass of one mole of a substance is known as Molar Mass. How to calculate the molar mass of H 2 O? Water is made up of hydrogen and oxygen, with a formula of H 2 O. There are 2 moles of Hydrogen and 1 moles of Oxygen.
