Answer:
397 L 
Explanation:
Recall the ideal gas law: 

If temperature and pressure stays constant, we can rearrange all constant variables onto one side of the equation: 

The left-hand side is simply some constant. Hence, we can write that: 

Substitute in known values: 

Solving for <em>V</em>₂ yields: 

In conclusion, 13.15 moles of argon will occupy 397* L under the same temperature and pressure. 
(Assuming 100 L has three significant figures.)
 
        
             
        
        
        
In order to determine the number of protons in 20.02 mol of Ne, we use Avogadro's number to convert the number of moles to number of atoms, 1 mol = 6.022 x 10^23 atoms. From there, we must know the number of protons in a Neon atom, which is 10. Thus, the formula will be:
(20.02 mol Ne)x(6.022 x 10^23 atoms/mol)x(10 protons/1 atom Ne) = 1.2056 x 10^26 protons
