A tank contains a mixture of 3.0 mol of nitrogen 2.0 mol of oxygen and 1 mol of carbon dioxide at 25 degrees and a total pressure of 10 ATM calculate the partial pressure in torr of each gas?

• chemistry -

The pressure of a gas is affected by the number of particles and not affected by the kind of gas it is. What does this fact tell us about ideal gases?

• chemistry -

XN2 = moles N2/total moles.
XCO2 = same thing
XO2 = same

pN2 = XN2*Ptotal
pCO2 = XCO2*Ptotal
pO2 = XO2*Ptotal
