This is an example of a chemical property.
There are 8 neutrons. The mass number subtracted by the atomic number gives you neutrons. if your continuing with isotopes, find the average mass of Oxygen 16
The charge on one mole of electrons = 96485 C = 1 Faraday
so if charge is 96485 C the moles of electrons are 1 = 6.023 X 10^23 electrons
if charge is 1 C the number of electrons = 6.023 X 10^23 / 96485
If charge is 50 micro C the number of electrons
= 6.023 X 10^23 X 50 X 10^-6 / 96485
= 3.12 X 10^14 electrons
Ethanol is produced by the fermentation of the sugar of plants and it can be used as a fuel
in brasil they have a mass culture of using ethanol mixed with other hydrocarbons called biofuel
hope that helps
