Find the no. Of electrons in 1gm of water and find the charge on them

for 1 molecule of water contain:

2 atoms of hidrogen = 2 electrons

1 atom of oxygen = 8 electrons
- - - - - - - - - - - - - - - - - - - - - - - - - - (+)
total = 10 electrons

1 gram of water = 1/18 mole = 1/18 * 6.02 * 10^23 molecules

total number of electrons in 1 gram of water is

N = 1/18 * 6.02 * 10^23 * 10

N = 3.34 * 10^23 electrons



q = N e

q = 3.34 * 10^23 * 1.6 * 10^-19

q = 53440 Coulomb
