Oxygen gas contained in a 1.35 L vessel is transferred to 755 mL vesse

1.	Oxygen gas contained in a 1.35 L vessel is transferred to 755 mL vessel. The initial pressure was 515 mmHg and the temperature was 34 degrees Celcius. What is the new pressure? a755 mmHg b0.921 atm c921 mmHg d0.755 mmHg
Answer» nitial Volume, V1 = 1.35 LNew Volume, V2 = 755 mL = 0.755 LInitial pressure, P1 = 515 mm HgTo Find:New pressure of the oxygen GAS.Calculation:- Applying BOYLE's LAW to the given condition, we get:P1 × V1 = P2 × V2⇒ P2 = P1 × V1/V2⇒ P2 = 515 × 1.35/0.755⇒ P2 = 920.86 mm Hg ≈ 921 mm Hg- So, the new pressure of the oxygen gas is 920.86 mm Hg.- HENCE, the correct answer is option (C) 921 mm Hg.
