What three conversion factors are often used in mole conversions?
moles = grams/molar mass.
moles = M x L
1 mole = 6.022 x 10^23 molecules.
Surely there are others.
The three conversion factors that are often used in mole conversions are:
1. Avogadro's number: 1 mole = 6.022 x 10^23 particles (atoms, molecules, ions, etc.)
2. Molar mass: 1 mole = mass of substance in grams
3. Volume at standard temperature and pressure (STP): 1 mole of gas = 22.4 liters (L)
In mole conversions, three common conversion factors are frequently used:
1. Avogadro's Number: This conversion factor is used to convert between the number of moles and the number of particles (atoms, molecules, ions, etc.). Avogadro's Number (6.022 x 10^23) represents the number of particles in one mole of a substance. To convert from particles to moles, divide the given number of particles by Avogadro's Number. To convert from moles to particles, multiply the given number of moles by Avogadro's Number.
2. Molar Mass: This conversion factor is used to convert between the number of moles and the mass of a substance. The molar mass represents the mass of one mole of a substance and is expressed in grams per mole (g/mol). To convert from grams to moles, divide the given mass by the molar mass. To convert from moles to grams, multiply the given number of moles by the molar mass.
3. Stoichiometric Ratios: These conversion factors are used in mole conversions when dealing with chemical reactions. Stoichiometry is the study of the quantitative relationships between substances in a chemical reaction. The coefficients in a balanced chemical equation can be used as conversion factors to relate the number of moles of one substance to another. For example, if you have the balanced equation 2H2 + O2 -> 2H2O, the stoichiometric ratio between hydrogen gas (H2) and water (H2O) is 2:2, which means that for every 2 moles of H2, 2 moles of H2O will be produced.
These three conversion factors are essential in performing mole conversions and provide a way to relate the number of moles to particles, mass, and other substances involved in chemical reactions.
