Answer:
The chemical symbol will be "[tex]_{29}^{63.5}\textrm{Cu}[/tex]".
Explanation:
The given values are:
Current,
I = 2.50 amps
Time,
t = 2 hr
or,
= 7200 sec
Metal deposited,
W = 5.93 gm
As we know,
⇒ [tex]W=Z\times i\times t[/tex]
or,
⇒ [tex]Z=\frac{W}{i\times t}[/tex]
On putting the given values, we get
⇒ [tex]=\frac{5.93}{2.5\times 7200}[/tex]
⇒ [tex]=3.2945\times 10^{-4}[/tex]
hence,
⇒ [tex]Atomic \ mass=Z\times electrons\times 96500[/tex]
⇒ [tex]=3.2945\times 10^{-4}\times 2\times 96500[/tex]
⇒ [tex]=63.5[/tex]
Thus the above is the right answer.
