Mole Conversions: Dimensional Analysis

Mole conversions using dimensional analysis use the idea that an equality such as 1 meter = 100 centimeters can be expressed as two fractions called unit conversions that are equivalent to each other and equivalent to 1.

For the equality 1 m = 100 cm the conversion factors are 1 m/100 cm or 100 cm/1 m.

Important information used:

• molar mass can be defined as the mass of one mole of a substance.
• particles refer to atoms, molecules, and formula units for elements, molecular compounds and ionic compounds respectively.
• molar volume is defined as the volume of one mole of a substance. A common molar volume used is the molar volume of a gas at standard temperature and pressure, 22.4 liters/mole.
