P1V1 = P2V2

16mL x 1 atm = P2 x 7.5mL

16 mL.atm/7.5 mL = P2

2.1333 atm = P2

or 2.1 atm = P2

1 atm = 10 meter

2.1 atm 1 atm = x meter

1.1 atm = x

x = 11 meters

Yes, you should subtract 1 atm because youre starting at sea level where the pressure is 1 atm and you havent traveled any distance below water yet.

Hope this helps. For every 32 feet below sea level the pressure increases one atmosphere.
