Answer» zinc in 2kg of new alloy=(5/13)+(5/8)=105/104kg coppper in 2kg of new alloy=(8/13)+(3/8)=103/104kg ratio of zinc and copper in the resulting alloy is' =(105/104)/(103/104) =105/104 weight of copper in the alloy 15.2 weight of copper in the alloy = 15.2 weight of copper = 15.2 15.2 is the right answer weight of copper in the alloy =15.2 answer |
