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.
C i think but you should pick it anyway
3.08*10^23 ions of Na+ and Cl- will be present in 30g of NaCl.
Weight of NaCl is equal to sum of weight of one mole of sodium and one mole of chloride.
Mathematically, it can be represented as -
1 mol (Na) + 1 mol (Cl)
= 23.0+ 35.5
= 58.5 g/mol
In 58.5 gram of NaCl, there is one mole of Na or 6.02*10^23 ions
In one gram of NaCl, there will be
=6.02*10^23/58.5 sodium ions
In 30 grams of NaCl, the number of sodium ions will be -
(6.02*10^23*30)/ 58.5
=3.08*10^23 ions
