How do you convert molecules to moles?

Answer 1

To convert the number of atoms to moles:

You need the number of atoms in a substance which is usually given. Ex. 1.65 × 1024 atoms of Magnesium. Then the formula is as follows:

# of atoms ÷ (Avogrado's Constant) = # moles

1.65 × 1024 atoms ÷ (6.02 × 1023) = 2.74 moles of Mg

Answer 2

To convert molecules to moles, you first determine the number of molecules by counting them or using Avogadro's number (6.022 x 10^23 molecules per mole). Then, divide this number by Avogadro's number to find the corresponding amount in moles.

Answer 3

To convert molecules to moles you have to divide the molecules(particles) by Avogadros Number(6.02x10^23).

ex:how many moles of CO2 in 3.9x10^22 molecules?

3.9x10^22/6.02x10^23=6.47 moles of CO2

Answer 4

A mole is just a word that describes a quantity, like a dozen.

If you have a dozen of something, you have 12 of them. If you have a mole of something, you have 6.022 * 10^23 of them. (That's the digits 6022 followed by 20 zeroes.)

So, divide the number of atoms you have by (6.022 * 10^23).

Answer 5

There are 6.022 x 1023 atoms in 1 mole (note this is scientific notation, the actual number would be 602200000000000000000000). okay now let's say I wanted to convert 9.23 moles of oxygen to atoms, you would set it up, so that your multiplying what you want to convert to your designated conversion over the unit you are converting it from [9.23 moles X (6.022 x 1023)/1 mole], then the moles cancel out since they're are two of them involved [9.23 moles X (6.022 x 1023)/ 1 mole], then you can take away the 1 since it won't change the equation [9.23 X (6.022 x 1023)], now if you have a calculator with many of the advanced features then you will type in: 9.23 X (6.022 X 10^23) or: 9.23 X (6.022 X 10 E 23) which will roughly turn out to be 5.56 X 1025.

Answer 6

Definition: one mole Is the amount of substance hat contains as many particles ad there are in exactly 12g ( 0.0012kg) of the c12 isotope.

Having said that, I move on to the CONVERSION:

In order to determine the number of entities (may be atoms, molecules,ions ,etc) precisely, the mass of a carbon atom was determined with a mass spectrometer and was equal to : 1.992648. A mole of carbon weighs 12g.

Therefore, number of atoms = (12g/mole of C12)/(1.992648 x 10^-23 g / C12 atom)

i.e =( molar mass (of desired atom) per mole ) / (mass of an induvidual atom in grams).

Hope I helped.

Answer 7

To convert atoms to moles you need to take the amount of atoms that you have, multiply it by 1 mol/ Avagadros number. That should give you the proper amount of moles.

Answer 8

Multiply number of moles by the molecular mass of the element or compound

Answer 9

Avogadro's number:

# of moles x 6.02 × 1023 = atoms, moleculs or ions

Answer 10

there are 6.02 x 1023 atoms in a mole
