Open in App
Solution

Calculation of the number of ions in a solution:

Step 1: Calculating the number of moles

  • The mole is used as a measurement or a basic unit that helps in calculating the amount of substance present in the given sample.
  • To calculate the number of ions, one must first calculate the number of moles of a given element.

Numberofmoles(n)=GivenmassMolecularmass

Step 2: Calculating the number of ions

  • After calculating the number of moles, the number of ions will be equal to the product of the number of moles and Avogadro’s number.

Numberofions=(numberofmoles)×NAwhereNA=Avogadronumber

Hence, the number of ions in a solution can be calculated as above , using the mole concept as; Numberofions=(numberofmoles)×NA.
