Answer:
6 x (10)^26 electrons.
Step-by-step explanation:
1 mole = 18 gr
1 gm =1/18 mole
1 kg = 1000/18 mole
Now , 1 mole of any compound = 6.022 x (10)^23 atoms.
Therefore, 1 kg of H20= (1000/18)*(6.022 x (10)^23) atoms
Roughly , 3.34 x (10)^25 molecules
And each molecule has 18 electrons
Therefore, 6 x (10)^26 electrons.
Thank you.
