1.	0.The molarity of pure water is:(1) 100 M(3) 50 M(2) 55.5 M(4) 18M
Answer» The density of water is approximately 1000 g/L and its molar mass = 8.02 g/mol (or 1/18.02=0.055mol/g).Therefore, the molar concentration of water is: (H2O) = 1000 g/L / (18.02 g/mol) =55.5mol/L.(molar concentration=density/molar mass)
