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 in liters of NO₂ gas collected over water at 25.0 °C when 2.97 g of copper is added to excess nitric acid if the total pressure is 726.0 mmHg. The vapor pressure of water at 25.0 °C is 23.8 mm Hg.
