7. At a pressure of 3800 torr, a sample of gas occupies 40 liters. What volume will the

same sample occupy at 1.0 atmosphere?

V₂ = 200 L

Explanation:

Given dа ta:

Initial pressure = 3800 torr (3800/760 = 5 atm)

Initial volume = 40 L

Final volume = ?

Final pressure = 1.0 atm

Solution:

P₁V₁ = P₂ V₂

V₁ = Initial volume

P₁ = Initial Pressure

V₂ = Final volume

P₂ = Final Pressure

Now we will put the values in formula.

P₁V₁ = P₂ V₂

V₂ = P₁V₁ / P₂

V₂ = 5 atm * 40 L / 1.0 atm

V₂ = 200 atm. L / 1.0 atm

V₂ = 200 L
