it is aproblem on eudiometry which ismeasuring instrument consisting of a graduated glass tube for measuring volume changes in chemical reactions between gases.
on passing 25ml of a gaseous mixture of N2 and NO over heated copper only NO is absorbed
25 ml of N2 + NO
20 ml remained is N2
NO is absorbed
therefore 20% NO and 80% N2 are present.
