@Abhisar
OpenStudy (abhisar):
You tell me, this is very easy.
OpenStudy (abhisar):
How many electrons in 1 mole?
OpenStudy (aaronandyson):
Do I have to multiple the charge,by avogardos number?
OpenStudy (abhisar):
Yes!

Getting it?
OpenStudy (aaronandyson):
In the question the charge is given as "negative" and yes.
OpenStudy (abhisar):
I know, charge on electron is negative and proton is positive.
OpenStudy (aaronandyson):
so 1.6*6022?
OpenStudy (aaronandyson):
1.6*10^-19 times 6.022*10^23
so it will bw 10^4 cuz -19+23 = 4.

Correct!
\(\sf-1.6 \times 10^{-19} \times 6.022 \times 10^{23}\)
OpenStudy (aaronandyson):
so,
16*6022?
OpenStudy (abhisar):
\(\sf -9.6 \times 10^4\)
OpenStudy (aaronandyson):
How'd you get that?
OpenStudy (abhisar):
Just multiply \(\sf-1.6 \times 10^{-19} \times 6.022 \times 10^{23}\)

-1.6 x 6.022 = ?
OpenStudy (aaronandyson):
9.635
OpenStudy (abhisar):
Yes, and finally \(\sf 10^{-19} \times 10^{23} = 10^{23-19}=?\)
OpenStudy (aaronandyson):
10^4
OpenStudy (abhisar):
So, the final answer is -9.6 x \(\sf 10^4\)
