(4. The volume of a sample of carbon monoxide is 354 mL at 3.52 atm. What will the volume be when the pressure
is reduced to 1.85 atm, assuming the temperature is constant?

V₂  = 673.56 mL

Explanation:

Given data:

Initial volume of gas = 354 mL

Initial pressure = 3.52 atm

Final volume of gas = ?

Final pressure = 1.85 atm

Solution:

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

3.52 atm × 354 mL = 1.85 atm × V₂

V₂  = 1246.08 atm. mL /1.85 atm

V₂  = 673.56 mL
