Avogadro's Number is 6.02 x 10e23 Questions by John Garner

Converting molecules to moles.

To find how many moles are in 100 water molecules,

100 water molecules ×

(

1 mole water

6.02×10²³ water molecules

)

= 1.66× 10^-22 moles water

Teacher Question #1

jgarner7 — 2015-03-04 10:16:13 UTC

How should conversion factor problems be set up to show the work?

Student Question

jgarner7 — 2015-03-04 10:16:28 UTC

Why does only one mole fit in a mole hole?

Teacher Question #2

jgarner7 — 2015-03-04 10:16:46 UTC

How do conversion factors where 1 mole = 6.02 X 10²³ allow you to change from molecules(atoms) to moles or vice versa?

Teacher Question #3

jgarner7 — 2015-03-04 10:17:04 UTC

How are scientific numbers entered into a scientific calculator?

Teacher Question #4

jgarner7 — 2015-03-04 10:17:15 UTC

When do we use the conversion factor

(1 mole/ 6.02 X 10²³ molecules) and when do we use

(6.02 X 10²³ molecules/1mole)?

The conversion factor 1 mole/ 6.02x10^23 molecules is used to convert from the number of molecules of a compound to the number of moles.

The conversion factor 6.02x10^23 molecules/1 mole is used to convert from moles to molecules.

The conversion factors 1 mole/ 6.02x10^23 molecules and 6.02x10^23 molecules/1 mole have an infinite number of significant digits because Avagadro's number is equal exactly to 1 mole. Conversion factors work because they are equal to exactly 1. After converting it is important to incorporate significant digits rules in determining the answer

Avogadro was born in 8/9/776 and died in 7/9/1856.

Avogadro's full name is Lorenzo Romano Amedeo Carlo Avogadro did Quaregna e di Certetto.

We use the conversion factor 1mole/ 6.02 x 10^23 when converting molecules to moles.

The saying goes "one mole fits in a mole hole" because 1 mole/ molecular mass = 1

Avagadro's number is the number of molecules in a mole.
