A salt crystal has a mass of 0.12 mg. How many NaCl formula units does it contain?
Here, we are going to calculate the number of NaCl formula units present in a salt crystal of mass 0.12 mg.
One mole of any species is that quantity in number having a mass equal to its atomic or molecular mass in grams.
The number of particles (atoms, molecules or ions) present in 1 mole of any substance is fixed, with a value of 6.022 × 1023. This is an experimentally obtained value. This number is called the Avogadro Constant or Avogadro Number.
