A50.0 ml sample of a cu(no3)2 solution, which
is a blue solution, and a naoh solution, which is
colorless, are combined forming a blue cu(oh)2
(molar mass 81.5) precipitate. the 0.815 g
precipitate is collected through filtration, and the
colorless filtrate is set apart. what is the
concentration of the original cu(no3)2 solution?
(a) 0.10 m
(b) 0.20 m
(c) 0.40 m
(d) the concentration of cu(no3)2 solution
cannot be determined because it was the
excess reactant.

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)
