Moles to Particles

Front

What is Avogadro's number?

Back

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

Front

How do you convert moles to particles?

Back

Multiply the number of moles by Avogadro's number (6.02 x 10^23).

Front

How many atoms are in 1 mole of any element?

Back

6.02 x 10^23 atoms.

Front

What is the formula to calculate the number of moles from particles?

Back

Number of moles = Number of particles / Avogadro's number.

Front

If you have 2 moles of a substance, how many particles do you have?

Back

2 moles x 6.02 x 10^23 = 1.204 x 10^24 particles.

Front

What unit is used to measure the amount of substance in chemistry?

Back

Mole (mol).

Front

How many moles are in 12.04 x 10^23 atoms of carbon?

Back

2 moles (since 12.04 x 10^23 / 6.02 x 10^23 = 2).

Front

What is the relationship between moles and grams?

Back

Moles = Mass (g) / Molar mass (g/mol).

Front

How many moles are in 3.01 x 10^22 atoms of magnesium?

Back

0.050 moles (3.01 x 10^22 / 6.02 x 10^23).

Front

What do you need on the bottom of the conversion factor when converting particles to moles?

Back

Avogadro's number (6.02 x 10^23 particles/mole).
