Answer:
P₁ = ⅔ P₀
Explanation:
For this exercise we can use the ideal gas equation
PV = n R T
let's write the equation for the initial point, where we will use the subscript o and the end with subscript 2
Suppose the temperature does not change in the process
P₀V₀ / n₀ = P₁V₁ / n₁
They tell us that
V₁ = V₀ / 2
n₁ = n₀ / 3
we substitute
[tex]P_o \frac{V_o}{n_o} = P_1 \frac{V_o}{2} \frac{3}{n_o}[/tex]
P₀ = [tex]\frac{3}{2}[/tex] P₁
P₁ = ⅔ P₀
