Equipped diver is at the depth of 21 m, where the pressure is 2,1 bar(3,1 abs). The diver breathes air that is pressurized to 2 bar. What would the final lung capacity be if the diver held their breath while ascending to the surface? diver lung capacity is 5.1 L and temperature is constant

p1v1=p2v2

P1= 2,1bar (3,1 bar absolute), V1=5.1L P2= 1 bar

V2 = 15,3L?
is that right'?
