Question

18.7 L N2 at 25 °C and 125 kPa and 38.3 L O2 at 25 °C and 125 kPa were transferred to a tank with a volume of 6.75 L. What is the total pressure at 59 °C?

Answer 1

because were assuming ideal gas behaviour and the gases were at the same temp and pressure (initially), you can add the volumes of the gases and use them as 1.

18.7 L N2 + 38.3 L O = 57.0 L

57.0 L at 25 °C and 125 kPa

Use the equation i posted in the previous question to find the final pressure.

Answer 2

Thank you so much!

Answer 3

no problem !
