1 of 5
How to calculate mass of one ion (kg)
Mr/1000
Ans/av. constant
2 of 5
Calculate velocity of ^138Ba^+
KE = 2.77 x 10^-15 J
v=sqrt(2KE/m)
1.55 x 10^5 ms^-1
3 of 5
Calculate Mr of ion produced via electrospray KE of 3 x10^-15 J and v of 1.5 x10^5ms^-1
m=2KE/v^2
convert kg - g then times by av. constant
-1
159.6
4 of 5
63-Cu;65-Cu
Accelerated through flight tube
^63Cu^+ took 1.4242 x 10^-5 s
Find time of ^65Cu^+
mass of both
KE and distance the same - put KE equations equal to each other and set d to 1
solve for t
1.45 x 10^-5s
