there's two questions :)
Enter your answer in the provided box. The solubility of KNO3 is 155 g per 100.0 g of water at 75°C and 38.0 g at 25°C. What mass (in grams) of KNO3 will crystallize out of solution if exactly 275.0 g of its saturated solution at 75°C is cooled to 25°C The solubility of N, in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 x 10 mol/L. A deep- sea diver...
The solubility of N2 in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 × 10-4 mol/L A deep- sea diver breathes compressed air with the partial pressure of N2 equal to 4.3 atm. Assume that the total volume of blood in the body is 5.4 L. Calculate the amount of N2 gas released (in liters at 37°C and 1.00 atm) when the diver returns to the surface of the water, where the partial pressure of...
The solubility of N2 in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 x 10 mol/L. A deep- sea diver breathes compressed air with the partial pressure of N2 equal to 3.6 atm. Assume that the total volume of blood in the body is 4.7 L. Calculate the amount of N2 gas released (in liters at 37°C and 1.00 atm) when the diver returns to the surface of the water, where the partial pressure of...
Enter your answer in the provided box. The volume of a bubble that starts at the bottom of a lake at 4.55°C increases by a factor of 11.0 as it rises to the surface where the temperature is 20.25°C and the air pressure is 0.955 atm. Assuming that the density of the lake water is 1.00 g/cm3, determine the depth of the lake. 96.620 m
2. [0pt] In scuba diving, a regulator is used so that the pressure of the air the diver breathes is close to that of the ambient water. A reckless swimmer decides to use a hose sticking out of the surface to breathe underwater while diving in a lake. When the air pressure in the lungs is at a pressure of around 0.160 atm below the ambient pressure, lung injury may occur. Find the depth at which the swimmer would experience...
In scuba diving, a regulator is used so that the pressure of the air the diver breathes is close to that of the ambient water. A reckless swimmer decides to use a hose sticking out of the surface to breathe underwater while diving in a lake. When the air pressure in the lungs is at a pressure of around 0.145atm below the ambient pressure, lung injury may occur. Find the depth at which the swimmer would experience such a pressure...
A scuba diver is 45 m below the surface of a lake, where the
temperature is 5°C. He releases an air bubble with a volume of 10
cm3. The bubble rises to the surface, where the
temperature is 25°C. Assume that the air in the bubble is always in
thermal equilibrium with the surrounding water, and assume that
there is no exchange of molecules between the bubble and the
surrounding water. What is the volume of the bubble right before...
Enter your answer in the provided box. The solubility of CO2 in water at 25°C and 1 atm is 0.034 mol/L. What is its solubility at a partial pressure in air of 0.00057 atm? Assume that CO2 obeys Henry's law. mol / L
A scuba diver is 35 m below the surface of a lake, where the temperature is 5°C. He releases an air bubble with a volume of 16 cm3. The bubble rises to the surface, where the temperature is 25°C. Assume that the air in the bubble is always in thermal equilibrium with the surrounding water, and assume that there is no exchange of molecules between the bubble and the surrounding water. What is the volume of the bubble right before...
A scuba tank is filled with air to a gauge pressure of 204 atm when the air temperature is 33 ∘C. A diver then jumps into the ocean and, after a short time on the ocean surface, checks the tank's gauge pressure and finds that it is only 196 atm. Assuming the diver has inhaled a negligible amount of air from the tank, what is the temperature of the ocean water? Express your answer to two significant figures and include...
