Example \(\PageIndex{1}\) Tin metal reacts with hydrogen fluoride to produce tin (II) fluoride and hydrogen gas according to the following balanced equation. May 08, 2018 · To convert particles (atoms or molecules) to moles: Take the number of particles and divide them by Avogadro’s number. To convert moles to particles (atoms or molecules): Take the number of moles and multiply them by Avogadro’s number. To convert grams to moles: Divide the initial mass of the substance by the compound’s molar mass (listed in the periodic table of the elements). To convert moles to mass: Mole Conversions Worksheet There are three mole equalities. They are: 1 mol = 6.02 x 10 23 particles 1 mol = g-formula-mass (periodic table) 1 mol = 22.4 L for a gas at STP Each equality can be written as a set of two conversion factors.A common technique involves using conversion factors to convert from one unit to another. Units that appear in the numerator and denominator of a fraction can be canceled out. For example, converting 2 moles of carbon monoxide to grams involves multiplying by a conversion factor: 2 mol CO • 28.01 g CO = 56.02 g CO. 1 mol CO
