Question

There are 4.288 x 10^24 particles of sand in a bucket you

have from the beach. How many moles of sand do you
have?

Answer 1

7.12 moles of sand you have in the bucket

Step-by-step explanation:

Moles are defined as a determined amount of particles. To relate moles with particles it is used Avogadro's number (6.022x10²³ particles / mole).

That means in 1 mole of a determined particle you will have 6.022x10²³ particles.

As in the bucket there are 4.288x10²⁴ particles:

4.288x10²⁴ particles * (1mole / 6.022x10²³ particles) =

7.12 moles of sand you have in the bucket
