Answer:
Chlorine (Cl) in its lowest energy state (called the ground state) has seven electrons in its outer shell. Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. ... In the formation of an ionic compound, metals lose electrons and nonmetals gain electrons to achieve an octet.

<u>Answer:</u> The solubility of nitrogen gas in the sample is 
<u>Explanation:</u>
We are given:
Volume percent of nitrogen gas = 80 %
To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,
= Henry's constant = 
= partial pressure of nitrogen gas = 1.0 atm
Putting values in above equation, we get:

Solubility of nitrogen gas in the sample = 
Hence, the solubility of nitrogen gas in the sample is 
Hey☺..Here is your answer u r looking for
Copper (Cu) = 1 atom
Sulphur(S)=1 atom
Oxygen(O)= 4 atom
The number of atoms present in 80.156 grams of Ca is 1.204×10²⁴ atoms
<h3>Avogadro's hypothesis </h3>
From Avogadro's hypothesis,
1 mole of Ca = 6.02×10²³ atoms
But
1 mole of Ca = 40.078 g
Thus,
40.078 g of Ca = 6.02×10²³ atoms
<h3>How to determine the atoms in 80.156 g of Ca</h3>
40.078 g of Ca = 6.02×10²³ atoms
Therefore,
80.156 g of Ca = (80.156 × 6.02×10²³) / 40.078
80.156 g of Ca = 1.204×10²⁴ atoms
Thus, 1.204×10²⁴ atoms is present in 80.156 g of Ca.
