Moles = 9.03 x 10^23
             ----------------------
                6.02 x 10^23
 
           =      1.5 mole.

Hope this helps!

Answer:

Number of moles = 1.499 ≅(1.5 moles)

Explanation:

Given:

Number of particles in a given substance = 9.0310²³

To determine:

The number of moles corresponding to the given number of particles

Explanation:

1 mole of any substance contains Avogadro's number of particles

i.e. 1 mole = 6.02310²³ particles

Therefore, the number of moles corresponding to 9.03*10²³ particles would be:

\(= \frac{9.03*10^{23}\ particles * 1\ mole }{6.023*10^{23} \ particles} \\= 1.499 moles\)
