summarize the entire problem.
I had written in the mail that the prof. I also said that the charge, of course not, the electron is equal to
-19 To 10
1/1.6 ; coulomb. That is, the charge and there is unknown.
Thus the number of electrons in the entire charge of 1 C is given by 1/il value of this charge.
If I understand you do not return the result of 6.25 molt. to 10 because the exponent, as well as change of sign, is also decreased, the result obtained by you from 19 to 18.
The fact is that 1 / 1, 6 is equal to 0625 then you have to multiply by 10, but in scientific notation (with exponent) 0, .. We're like the cabbage and then is multiplied by 10 by moving the decimal point to the right (no more, or 6 .. but 6 ,..).
At this point, having multiplied everything by 10, you must take this into account by decreasing the exponent that would be multiplied by 19 18.Altrimenti becomes a bit 'too much.
Essentially this is the number: , 18
6,25 per 10 .
But You're not a teetotaler? If this were not more aware of the common earthen friendship because I can be purple on not with bitterness, but defer sull'astemio ever!
