Answer:
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
