Question

Determine o número de elétrons existente em uma carga de 2,5C?​

Answer 1

$\Large\boxed{\begin{array}{l}\sf Q= n\cdot\bf e\\\sf n\longrightarrow n^o~de~el\acute etrons\\\bf e\longrightarrow\sf carga~elementar\\\underline{\tt dados:}~\sf Q=2,5~C~n=?\\\underline{\rm soluc_{\!\!,}\tilde ao\!:}\\\sf Q=n\cdot e\implies n=\dfrac{Q}{e}\\\\\sf n=\dfrac{2,5}{1,6\cdot10^{-19}}\\\sf n=1,5625\cdot10^{19}~el\acute etrons\end{array}}$
