Question

A 1.24 L sample of gas at 759 mm Hg pressure is expanded until its volume is 2.02 L. What will be the pressure in the expanded gas sample (at constant temperature)?

my answer is 0.613 atm

Answer 1

pV =nRT so , if T constant pV = constant

p1V1=p2V2

p2 =p1V1/V2

here

p2= 759*1.24/2.02=466 mmHg
