Answer to Question #135686 in Physical Chemistry for Fatoumatta

Question

A sample of copper was analysed and found to contain two isotopes 63-copper and 66-copper. All the ions were accelerated and travelled through a flight tube.
63Cu+ ions took 1.4242 x 10^-5s.
How long would 66Cu+ ions take to travel along the same flight tube?

Answer 1

63Cu+ ions took 1.4242 x 10^-5s

Speed of ions depand on mass number So , 66Cu⁺ ion took higher time than 1.4242 x 10^-5 s .

Time Taken = 1.4242 x 10^-5 * 66 / 63 = 1.4242 x 10^-5 * 1.04 = 1.5 x 10^-5 s . Answer .

( Approx .)
