Avogadro’s number, molar mass, and the chemical formula of a compound are three useful conversion factors. What unit conversions can be accomplished using these conversion factors?

Avogadro's number (\(6.022 \times 10^{23}\)) is a fundamental constant that relates the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. It can be used for the following unit conversions: 1. Moles to particles: To convert from moles to particles (atoms, molecules, ions, etc.), multiply the number of moles by Avogadro's number. 2. Particles to moles: To convert from particles to moles, divide the number of particles by Avogadro's number.

Molar mass is the mass (in grams) of one mole of a substance. It is determined by summing the atomic masses of the elements in a compound, with each atomic mass weighted by the number of times the element appears in the compound. Molar mass can be used for the following unit conversions: 1. Moles to mass (grams): To convert from moles to grams, multiply the number of moles by the molar mass of the substance. 2. Mass (grams) to moles: To convert from grams to moles, divide the mass of the substance by its molar mass.

The chemical formula of a compound indicates the proportion of each element in the compound, providing information about the composition of the compound. It can be used for the following unit conversions: 1. Mass of one element to mass of another element in a compound: To convert the mass of one element in a compound to the mass of another element in the same compound, use the mole ratio from the chemical formula and the molar mass of each element. 2. Moles of one element to moles of another element in a compound: To convert the moles of one element in a compound to the moles of another element in the same compound, use the mole ratio from the chemical formula. 3. Mass percent of an element in a compound: To find the mass percent of an element in a compound, divide the mass contribution of that element (atomic mass multiplied by the number of atoms of that element in the compound) by the molar mass of the compound, and multiply the result by 100. In summary, Avogadro's number, molar mass, and the chemical formula of a compound can be used to accomplish various unit conversions related to moles, particles, mass, and composition.
