Mass of 1 ml of water 1 g as density of water 1.00 g/ml at 4° C. So, mass of 2.36 ml of water [tex]\frac{1}{2.36}[/tex] g= 0.423 g.
Molecular mass of water is 18 g which indicates 18 g water contains 6.023 X [tex]10^{23}[/tex] number of water molecules. So, 0.423 g of water contains [tex]\frac{6.023 X 10^{23} X 0.423 }{18} g[/tex] = 0.141 X [tex]10^{23}[/tex] number of water molecules= 1.41 X [tex]10^{22}[/tex] number of water molecules.
