Moles to Particles Flashcard

Front

What is the relationship between grams and moles in a conversion factor?

Back

To convert grams to moles, you need the molar mass of the substance in grams per mole.

Front

How do you calculate the number of moles from a given number of molecules?

Back

Use Avogadro's number (6.022 x 10^23) to convert molecules to moles by dividing the number of molecules by Avogadro's number.

Front

What is Avogadro's number?

Back

Avogadro's number is 6.022 x 10^23, which is the number of particles (atoms, molecules, etc.) in one mole of a substance.
