Hello,

I am working on the derivation that proves that the partial molar volume of an ideal gas is equal to the molar volume of an ideal gas.

I am following up to the point in the textbook where they set

(∂n/∂ni)nj = 1

where ni is the number of of moles of species i, and nj is the number of moles of species j ≠ i.

Attached is a photo of the derivation in the textbook

If n = n1+n2+n3+n4+n5
and you take the partial derivative of n with respect to, say n3 holding all the other subscripted n's constant, what do you get?
