Thanks. Still having trouble wrapping my head around that.
Is the difference that of the compressibility of the gases, or?

"The partial volume of a particular gas is the volume which the gas
would have if it alone occupied the volume.", do they mean that if
there were 21 molecules of oxygen and 79 molecules of nitrogen
compressed into a 1 CC container, if the nitrogen were removed, the
oxygen would be at its partial volume?

Is "the volume" they refer to 1 CC or 0.21 CC in my example?

(Last chem class was high school level in 1970; "molar fraction" is
still recognized.)

Is this a semantics test question?
