The volume of the vessel is reduced twice, and the number of molecules is reduced three times. How the pressure will change gas?​

     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

        P₀ =     P₁  

        P₁ = ⅔ P₀

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.
