To convert formula units to moles, you use Avogadro's number, which is 6.022 x 1023 formula units per mole. If you have the number of formula units, divide that number by Avogadro's number to get the number of moles.
We can use these ratios to determine what amount of a substance, in moles, will react with or produce a given number of moles of a different substance. The study of the numerical relationships between the reactants and the products in balanced chemical reactions is called stoichiometry.
A balanced chemical equation works like a recipe to that show the moles of reactants and products involved in the reaction. The coefficients (numbers before each chemical formula) are equivalent to the number of moles. E.g Burning hydrogen to produce water is read like this: 2 mol of hydrogen react with 1 mol of oxygen to produce 2 mol of water
Conversions Between Moles and Number of Particles. Using our unit conversion techniques, we can use the mole label to convert back and forth between the number of particles and moles.
29 lip 2021 · The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10 23 atoms, molecules, or formula units of that substance.
For covalent substances, the formula represents the numbers and types of atoms composing a single molecule of the substance; therefore, the formula mass may be correctly referred to as a molecular mass.
