1. The problem statement, all variables and given/known data The deepest part of the ocean is about 10,900 meters deep. Calculate the pressure at that depth in units of N/m^2. Mass density for seawater is 1030 kg/m^3. Then convert the pressure to the number of atmospheres given one atmosphere is 1.013x10^5 N/m^2. 2. Relevant equations pressure = mass density x gravity x height 3. The attempt at a solution p= (1030 kg/m^3)(9.8 m/s^2)(10,900 m) p= 1.10x10^8 N/m^2 1 atmosphere = 1.013x10^5 N/m^2 1.10x10^8 N/m^2 / 1.013x10^5 N/m^2 = 1086 atmospheres. I know that number is wrong. My guess is there are about 1.3 - 1.4 atmospheres of pressure there, but I can't get the math to find an exact number for that conversion. What is the best way to convert pressure to atmospheres?
