Hello guys, i have been wondering about this question for a while now,

Derive an equation for the density ( p in g/L ) of an ideal mixture of HNO3 and H2O in tearms of the mass fraction of HNO3 ( X Kg HNO3/Kg H2O )

this is what i have come up with but not quite sure if its correct

p = X P(HNO3) + (1-X) P(H2O)

Thanks
