Answer:
Explanation:
[tex]n = \frac{m}{M}[/tex]
[tex]n = \frac{1000}{4}[/tex]
= 250 moles.
N = n×6.02×[tex]10^{23}[/tex]
= 1.505×[tex]10^{26}[/tex]
Total charge = (1.505×[tex]10^{26}[/tex]) × (1.6×[tex]10^{-19}[/tex])
= 2.4×[tex]10^{7}[/tex] C.
Answer:
Number of electrons=2
charge of an electron, e=1.6*10^-19
Q=ne Q=2*1.6*10^-
-19
m=1kg=1000g
n=m/M=1000/4=250
N=nL
N=2*1.6*10^-19*250*6.02*10^23
N=4.8*10^7 C
