1 electron has a mass of 9.1 X 10-31 kg. How many electrons n does it take to make 1 kg?
(1 e)/(9.1 X 10-31 kg) = n/(1 kg)
So, n = 1.10 X 1030 electrons
Each electron has a charge of 1.6 X 10-19 C, where C stands for Coulombs. So, the n electrons have a charge of q = ne = (1.10 X 1030 electrons) X (1.6 X 10-19 C/electron) = 1.76 X 1011 C.
Answer:
c. 0 and 7
Step-by-step explanation:
The answer is 1/10 x (9a-23b)
Ur answer is 1369 that is ur answer hope it helped and hope u pass
The correct answer in this case would be A. There is only 1/8th percent chance of the spinner landing on 4.
