To answer this question, we need to know the total pressure at a depth of 3.1 m. The total pressure underwater is the sum of the atmospheric pressure and the pressure due to the water column above the diver.

1. First, we calculate the pressure due to the water column. The pressure due to a column of fluid is given by the equation P = ρgh, where ρ is the density of the fluid, g is the acceleration due to gravity, and h is the height of the fluid column. For water, ρ is approximately 1000 kg/m³, g is approximately 9.81 m/s², and h is 3.1 m. So, the pressure due to the water column is P = 1000 kg/m³ * 9.81 m/s² * 3.1 m = 30411 Pa = 0.3 atm (since 1 atm = 101325 Pa).

2. The atmospheric pressure at sea level is approximately 1 atm. So, the total pressure at a depth of 3.1 m is 1 atm (atmospheric pressure) + 0.3 atm (pressure due to water column) = 1.3 atm.

3. The partial pressure of a gas in a mixture is given by the total pressure multiplied by the fraction of the gas in the mixture. So, the partial pressure of the nitrogen in the air tank is 75.5% of the total pressure, or 0.755 * 1.3 atm = 0.9805 atm.

So, the partial pressure of the nitrogen at a depth of 3.1 m is approximately 0.98 atm.

A diver uses an air tank that contains 75.5 % nitrogen. Determine the partial pressure of the nitrogen at 3.1 m. Your answer should either be in atm or kPa. Leave a space between the value and the units. Example: 2.55 atm
