Converting from mass (grams) to moles: Divide your initial mass by the molar mass of the compound as determined by the periodic table.Converting from moles to mass (grams): Multiply your initial mole value by the molar mass of the compound as determined by the periodic table.Converting from volume (liters) to moles: Divide your initial volume by the molar volume constant, 22.4 L.Converting from moles to volume (liters): Multiply your mole value by the molar volume constant, 22.4L.Converting from particles (atoms, molecules, or formula units) to moles: Divide your particle value by Avogadro’s number, 6.02×1023. Remember to use parentheses on your calculator!Converting from moles to particles (atoms, molecules, or formula units): Multiply your mole value by Avogadro’s number, 6.02×1023.Mole-to-mole conversions: Use the coefficients from your balanced equation to determine your conversion factor. Be sure your units cancel out so you end up with the correct mole value.
