# How do you find the number of molecules in a mole?

## How do you find the number of molecules in a mole?

Converting between molecules and moles is done by either multiplying by or dividing by Avogadro’s number:

1. To go from moles to molecules, multiply the number of moles by 6.02 x 1023.
2. To go from molecules to moles, divide the numbers of molecules by 6.02 x 1023.

## How do you convert moles to molecules?

Take the number of particles and divide them by Avogadro’s number. To convert moles to particles (atoms or molecules): Take the number of moles and multiply them by Avogadro’s number.

How do you find the number of molecules?

Determine the mass of the substance, and its molar mass. Divide the given mass by its molar mass to get moles, then multiply times 6.022×1023molecules1mol .

How many carbon atoms are there in 0.5 moles of C2H4?

One mole of carbon contains 6.022×10²³ atoms of carbon. So, 0.5 mol of carbon will contain 6.022×12²³/2 = 3.011×10²³ atoms.

### How many molecules are there in 220g of CF4?
