A mixture of gases at a total pressure of 95 kPa contains N2, CO2, and O2. The partial pressure of the CO2 is 24 kPa and the partial pressure of the N2 is 48 kPa. What is the partial pressure of the O2?

Isn't the sum of the partial pressures equal to the total pressure?

I have no idea how to do these questions. So i don't know.

Reread my comment. See if you can work it from that. I will be happy to critique your thinking.

Thank you, that's what i did, And i got the answer right!!

the pressure 25.0 meters under water is 347 kPa, what is this pressure in bar?

12 ml of nitrogen gas is collected at 70.0 c the pressure in the container is 125 kpa what will be the volume of the gas stp ?
