- 4.36 kPa
Solution:- At constant volume, the pressure of the gas is directly proportional to the kelvin temperature.
Where the subscripts 1 and 2 are representing initial and final quantities.
From given data:
For final pressure, the equation could also be rearranged as:
Let's plug in the values in it:
So, the new pressure of the gas is 4.36 kPa.

Hey There!
Given that (NH4)2S is a Strong electrolyte.!!!
(NH4)2S ---> 2 NH⁴⁺ + S²⁻
The equation tells you that you get 2 amonium ions and 1 sulfide ion from each (NH4)2S
Hope that helps!
