Calculate the partial pressure of 24 g methane, 48 g of oxygen and 56 g of nitrogen contained in a 25L container. What is the total pressure.

Answer 1

change each of these gasses to moles.

then us PV=nRT
You didn't list a termperature, but you need it. Pressure of gasses is dependent on temperatuare.

partial pressure= moles*absolutetemp*gasconstant/volume

then the total pressure is the sum of the three gases partial pressures.

Answer 2

i am not given the temperature.

Answer 3

Then you cant work it.
