Answer:

To find the number of moles in 6120 ions of NaCl, we need to know the Avogadro's number, which represents the number of entities (atoms, ions, or molecules) in one mole of a substance. The Avogadro's number is approximately 6.022 x 10^23 entities per mole.

Given:

Number of ions = 6120

To calculate the number of moles, we divide the number of ions by the Avogadro's number:

Number of moles = Number of ions / Avogadro's number

Number of moles = 6120 / (6.022 x 10^23)

Calculating the result:

Number of moles = 1.02 x 10^(-20) mol

Rounded to two decimal places as requested:

Number of moles = 1.02E-20 mol

Therefore, the number of moles in 6120 ions of NaCl is approximately 1.02E-20 mol.
