A scuba diver begins to surface carrying a tank containing 4.0 L of a gas at 730 mm Hg. What volume will the gas occupy at 760 mm Hg?

O A. 3.8 L

OB. 4.2 L

O C. 120 mm Hg

O D. 920 mm Hg

3.8 L

Explanation:

From Boyle's law;

P1 V1 = P2 V2

P1 = initial pressure = 730 mm Hg

P2 = final pressure = 760 mm Hg

V1= Initial volume = 4.0 L

V2 = final volume = ?

V2 = P1 V1/P2

V2 = 730 × 4/760

V2 = 3.8 L

where are the choice options?

fe 55.85 g/mol and h2o 18.02 g/mol.
