Answer:
So 9g of water will be half of a mole. 1 mole of any substance contains 6 X 10 ^ 23 molecules. So half a mole will have about 3 X 10 ^23 molecules . Each molecule of water has ( 8 + 1+1) 10 electrons.

Answer:
H2O molar mass = 18
Given mass of H2O= 9g
No. Of moles =9/18 = 0.5 mol
No. Of electron in one H2O molecule = 2 + 8 = 10 e
Total no. Of electron = 0.5 mol × 10= 5 mol .
