Answer:
Around [tex]1.7752248*10^{20}[/tex]
Explanation:
First, let's convert those minutes in seconds;
[tex]1.58min*\frac{60s}{1min}=94.8s[/tex]
Now, let's convert from amperes to electrons per second using the conversion factor given by:
[tex]1A=6.242*10^{18} electrons-per-second[/tex]
So:
[tex]0.3A*\frac{6.242*10^{18} }{1A} =1.8726*10^{18} electrons-per-second[/tex]
Finally, multiply the previous result by the time in seconds:
[tex]Total-electrons=(1.8726*10^{18})*(94.8)=1.77522248*10^{20}[/tex]
