The volume of a gas is 450 ml when its pressure is 1.00 atm. if the temperature of the gas does not change, what is the pressure when its volume is changed to 2.00 l? use mc004-1.jpg. (a)0.225 atm (b)0.444 atm (c)2.25 atm (d)4.44 atm

Based on the question, it is evident that the question is based on Boyle's Law which we will use to find the answer necessary.
Now, Boyle's Equation: P₁V₁ = P₂V₂
     P₂ = P₁V₁  ÷  V₂
∴   P₂  =  (0.450 L × 1 atm) ÷ 2 L      [plz note that 450 ml = 0.450 L]
⇒  P₂  = 0.225 atm Thus, the pressure when the volume has increased to 2 L is 0.225 atm [OPTION A].

Ithink is a because if say increased in electronegativity
