If a scuba diver's lungs have a normal capacity of 4.9l at sea level (1.0 atm), what would be the volume of her lungs if the pressure at a depth of 50 ft is 975 mmhg?
i believe the answer is 3.8 l
can someone confirm and show formula and work

The volume at 975 mmHg is 3.8 L.
Explanation:
Given data:
Volume of lungs = 4.9 L
Pressure = 1 atm
Volume of lungs = ?
When pressure becomes = 975 mmHg
Solution:
First of all we will convert the pressure into atm.
975 mmHg × 1 atm/ 760 mmHg
975 × 0.00132 atm
1.3 atm
At one atm volume is 4.9L.
1 atm = 4.9 L
Let consider the volume at 1.3 atm is x,
x = 4.9L / 1.3 L× 1atm
x = 3.8 L
