2.66 moles

Explanation:

In order to get from particles to moles or moles to particles, use Avogadro's number (6.022*10^23). This number represents the amount of particles of anything in a mole of that substance.

(In other words, a mole of anything is just 6.022*10^23 of that thing. A mole of elephants is 6.022*10^23 elephants. A mole of oxygen atoms is 6.022*10^23 oxygen atoms.)

mol\es -> particl\es: multiply by Avogadro's number
particl\es -> mol\es: divide by Avogadro's number

We'll divide (1.6*10^24)/(6.022*10^23), and this will give us ~~2.66.
