The normality is the ratio of the equivalent to the volume of the solvent. To the mixture, 1.182 gms of magnesium should be added.
<h3>What is Normality?</h3>
Normality (N) is the grams or moles of solute per liter of solution.
Magnesium has 2 valence electrons in the outermost shell so,
1 mEq of Mg⁻² ions = atomic number of Mg ÷ valence electron
= 12 ÷ 2
= 6 mg
In a liter solution having 197 meq/l of Mg⁻²:
197 meq/l of Mg⁻² × 6 = 1182 mg
Therefore, 1.182 gms of magnesium ions should be added to the mixture.

Explanation:
An electronic air sampler is a device that is used by people to check apprehension of contamination having individuals with the help of certain volume of air sampling.
The Device is used for recording the chemical data of contamination and the real-time data is sampled and recorded and the data is processed and stored. The air sampling is done in two ways.
