Find out the mass of the copper that was removed from the penny. Presuming excess nitric acid, Compute the grams of copper (II) nitrate that must have formed in the reaction
Original penny weight: 3.0712g
After nitric acid bath: 2.1476g
Apparently presume to use the subsequent formula when determining this
Cu(s) + 4HNO3 (aq) -> Cu (NO3)2(aq) + 2H20(l) + 2NO2 (l)
