When copper metal is added to nitric acid, the following reaction takes place cu (s) + 4 hno₃ (aq) → cu(no₃)₂ (aq) + 2 h₂o (l) + 2 no₂ (g) calculate the volume of no₂ gas collected over water at 25.0 °c when 2.01 g of copper is added to excess nitric acid if the total pressure is 726 mm hg. the vapor pressure of water at 25.0 °c is 23.8 mm hg.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.
