Answer:

1.13moles

Explanation:

Given parameters:

Number of atoms = 6.777 x 10²³ atoms

Unknown:

Number of moles = ?

Solution:

A mole of a substance contains the avogadro's number of particles

6.02 x 10²³ particles = 1 mole

6.777 x 10²³ atoms will contain $\frac{ 6.777 x 10^{23} }{6.02 x 10^{23} }$ = 1.13moles
