The number of atoms in one mole of any substance is measured by Avogadro's number. The value of Avogadro's number is 6.023 x 10 ^23. It is named after scientist Avogadro who proposed this number. 12 grams of carbon-12 represents 1 mole of carbon-12. For this reason, the number of atoms present in 1 mole of any substance is 6.023 x 10 ^23. Therefore, the number of atoms present in 1 mole carbon-12 is 6.023 x 10^23.
(Answer) This unit is the number of atoms in 12 grams of carbon-12 and known as Avogadro's number.
 
        
             
        
        
        
pV = nRT
p = nRT/V 
p= 1 x 0.08205 x 1000/ 2
p = 41.025 Pa  
Edit: The unit should be atm instead of Pa, as pointed out by a nice human being.
