Question

17.5 l n2 at 25c and 125 kpa and 33.5 l o2 at 25 c and 125 kpa were transferred to a tank with a volume of 4.50 l. what is the total pressure at 45 c.

Answer 1

The total pressure in the tank at 45°C is 206 kPa.

To determine the total pressure in the tank, you can use the combined gas law, which states that
`P_1V_1/T_1=P_2V_2/T_2`, where P is pressure, V is volume, and T is temperature.

Given the initial conditions of nitrogen (
`N_2`) and oxygen (
`O_2`) in separate volumes and temperatures, and the final conditions in the tank with a specific volume at 45°C, you can use the combined gas law to find the final pressure. After substituting the given values into the equation, solving for the final pressure yields a value of 206 kPa.

This calculation considers the change in volume and temperature as the gases are transferred to the tank and mixed. The resulting total pressure in the tank at 45°C is 206 kPa, reflecting the equilibrium conditions of the gases in the given volume and temperature.
