2 g of brass containing Cu and Zn only reacts with 3M HNO_(3) solution. Following are the reactions taking place Cu(s) + HNO_(3) (aq) to Cu^(2+) (aq) +NO_(2)(g) + H_(2)O(I)Zn(s) + H^(+)(aq) + NO_(3)^(-)(aq) to NH_(4)^(+) + Zn^(2+)(aq) + H_(2)O(l)The liberated NO_(2)(g) was found to be 1.04 L at 25^(@)C and 1 atm [Cu=63.5 , Zn=65.4]The volume of HNO_(3) consumed during the reaction with brass is
