The answer will be 0.3 mole BOYLE'S LAW Given: V1=7.25 ; P1=0.75mole ; V2=20L ; P2=? Formula: P2= (P1)(V1)/V2 P2= (0.75mole)(7.25L)/20L *cancel the Litres* P2= 5.4375mole/20 P2= 0.27mole or 0.3mole Thank you :)

Avogadro's Law, at STP (standard temperature and pressure)

   V₁  =  V₂
  ----     -----
   n₁       n₂

Given:
   n₁ = 0.75 mol
   V₁ = 7.25 L
   n₂ = ?
   V₂ = 20 L

Solution:
  
   n₂ = V₂ n₁
         ----------
             V₁
   
   n₂ = (20 L) (0.75 mol)
          ------------------------
                 7.25 L
  
   n₂ = (2.76) (0.75 mol)
   
   n₂ = 2.07 mol of nitrogen gas
