conversion factor

Examples of conversion factor in the following topics:

• Strategy for General Problem Solving

  • To do this, one uses a conversion factor.
  • Identify conversion factors that will help you get from your original units to your desired unit.
  • Don't forget that if need be, you can flip a conversion factor.
  • The reciprocal 1/24 could be considered the reverse conversion factor for an hours-to-days conversion.
  • The term "conversion factor" is the multiplier, not divisor, which yields the result.

• Molar Ratios

  • Molar ratios, or conversion factors, identify the number of moles of each reactant needed to form a certain number of moles of each product.
  • The coefficients in a balanced equation can be used as molar ratios, which can act as conversion factors to relate the reactants to the products.
  • These conversion factors state the ratio of reactants that react but do not tell exactly how much of each substance is actually involved in the reaction.

• Mole-to-Mole Conversions

  • Mole-to-mole conversions can be facilitated by using conversion factors found in the balanced equation for the reaction of interest.
  • The relationship between two of the reaction's participants (reactant or product) can be viewed as conversion factors and can be used to facilitate mole-to-mole conversions within the reaction.
  • Each stoichiometric conversion factor is reaction-specific and requires that the reaction be balanced.

• Mass-to-Mole Conversions

  • Mass-to-mole conversions can be facilitated by employing the molar mass as a conversion ratio.
  • The molar mass value can be used as a conversion factor to facilitate mass-to-mole and mole-to-mass conversions.
  • The mass and molar quantities of a substance can be easily interconverted by using the molecular weight as a conversion factor.

• Mass-to-Mass Conversions

  • Mass-to-mass conversions cannot be done directly; instead, mole values must serve as intermediaries in these conversions.
  • The ratio of the coefficients of two of the compounds in a reaction (reactant or product) can be viewed as a conversion factor and can be used to facilitate mole-to-mole conversions within the reaction.
  • Therefore, for a mass-to-mass conversion, it is necessary to first convert one amount to moles, then use the conversion factor to find moles of the other substance, and then convert the molar value of interest back to mass.

• Using Molarity in Calculations of Solutions

  • It also uses conversion factors to convert between grams and moles and between milliliters and liters.
  • This video looks at how to use molarity as a conversion factor.

• Gas Stoichiometry

  • Note the final conversion factor.

• Acidity of Amines

  • The same factors that decreased the basicity of amines increase their acidity.
  • For complete conversion to the conjugate base, as shown, a reagent base roughly a million times stronger is required.

• Bond Energy

  • A useful site for unit conversions may be reached by clicking the following link (http://www.chemie.fu-berlin.de/chemistry/general/units_en.html).
  • Indeed, the fact that carbon forms relatively strong bonds to itself as well as to nitrogen, oxygen and hydrogen is a primary factor accounting for the very large number of stable organic compounds.

• Grob Fragmentation

  • An interesting and generally useful skeletal transformation, involving specific carbon-carbon bond cleavage with accompanying conversion of certain sigma-bonds to pi-bonds, is known as the Grob fragmentation.
  • Whenever functional group interactions occur through a chain of covalent bonds (sigma or pi), stereoelectronic factors will play an important role.
