Question

561 dm^3 of a gas at s.t.p. is filled in a 748 dm^3 container if temperature is constant calculate the percentage change in pressure required​

Answer 1

PiVi = PiiVii [Temp constant]

So 760*561 = 748*Pii

=> Pii = 760*561/748

=> Pii = 570

So, Initial pressure was 760mm

Changed pressure is 570mm

Therefore % change = change/initial * 100

=> 190/760 * 100 = 25%
