WebJun 2, 2024 · Avogadro's number is one of the most important constants used in chemistry.It is the number of particles in a single mole of a material, based on the number of atoms in exactly 12 grams of the isotope carbon-12. Although this number is a constant, it contains too many significant figures to work with, so we use a rounded value of 6.022 x … WebWorking out the mass of a mole of a substance. Easy! Work out the relative formula mass, and then add the unit "grams". Example 1: The mass of 1 mole of water, H2O. The relative formula mass of water, H 2 O = (2 x 1) + 16 =18. 1 mole of water, H 2 O, weighs 18 g. Example 2: The mass of 1 mole of sodium carbonate crystals, Na2CO3.10H2O.

Basically it says there are 98.08 grams per 1 mole of sulfuric acid. If we're converting from grams of sulfuric acid to moles of sulfuric acid, we need to multiply by the reciprocal of the molar mass to do so, or 1 mole/98.08 grams. Hope that helps.
