A scuba diver is using scuba gear to breathe under water. The pressure on her lungs is 2.5 atm and her lung volume is 4.4 L. Wha
nikdorinn [45]

Answer:

<h2>2.44 L</h2>

Explanation:

The volume can be used by using the formula for Boyle's law which is

P_1V_1 = P_2V_2 \\

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the final volume

V_2 =  \frac{P_1V_1}{P_2}  \\

We have

V_2 =  \frac{2.5 \times 4.4}{4.5}  =  \frac{11}{4.5}  \\  = 2.444444....

We have the final answer as

<h3>2.44 L</h3>

Hope this helps you
