1. The problem statement, all variables and given/known data "At the surface of a freshwater lake the air pressure is 1.1 atm. At what depth under water in the lake is the water pressure 4.5 atm?" 2. Relevant equations I used the equation Pgauge = Dgh 3. The attempt at a solution I converted my atm to Pascals--> (4.5)(100000) = 450000 Pa Pguage = Dgh Pguage = (1000)(9.8)(h) -I used 1000, the density of water, but I'm not sure that is the right info to use for D! Then I solved for h. h = 450000/ (10000x9.8) h = 45.92 I got it incorrect though. Can anyone offer any insight? Thanks!
