Flashcardizz: Moles to Particles Conversions

Front

What is a mole?

Back

A mole is a unit of measurement in chemistry that represents 6.02 x 10^23 particles (atoms, molecules, ions, etc.).

Front

How do you convert moles to particles?

Back

To convert moles to particles, multiply the number of moles by Avogadro's number (6.02 x 10^23).

Front

What is Avogadro's number?

Back

Avogadro's number is 6.02 x 10^23, which is the number of particles in one mole of a substance.

Front

If you have 3 moles of a substance, how many particles do you have?

Back

You have 3 moles x 6.02 x 10^23 particles/mole = 1.81 x 10^24 particles.

Front

What is the conversion factor for grams to moles?

Back

The conversion factor is the molar mass of the substance (grams per mole).

Front

How do you convert grams to moles?

Back

To convert grams to moles, divide the mass of the substance in grams by its molar mass.

Front

What do you need to convert moles to grams?

Back

You need the molar mass of the substance.

Front

How many moles are in 1.204 x 10^24 atoms of carbon?

Back

1.204 x 10^24 atoms / 6.02 x 10^23 atoms/mole = 2 moles.

Front

What is the relationship between moles and molecules?

Back

1 mole of any substance contains 6.02 x 10^23 molecules.

Front

If you have 2.5 moles of water (H2O), how many molecules do you have?

Back

2.5 moles x 6.02 x 10^23 molecules/mole = 1.51 x 10^24 molecules.
