Calculate the number of different atoms in 0.2 mol ethene

1.204 × 10²³

Explanation:

The number of atoms in a mole is always 6.022 × 10²³, known as Avogadro's number or Avogadro's constant.

To convert moles to atoms, multiply the molar amount by Avogadro's number.

(6.022 × 10²³) × 0.2

         = 1.204 × 10²³

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
