Web8 apr. 2024 · Therefore, it follows that 1000 mL (one liter) of water will contain 1000 g of water molecules. And since the molar mass of water is 18 g per mol (18 g/mol), we can convert the 1000 g of water to moles of water by multiplying 1000 g of water by the ratio (1 mol/18 g). Thus, 1000 g x (1 mol/18 g) = 55.6 mol. WebLet's go back to conductivity. Conductivity is an index of how easy it is for electricity to flow. In water, it is the ions that pass electricity from one to the next. This means that the more Na + and Cl - contained in water the more electricity is carried, and the higher the conductivity. To sum up, if we know the conductivity of a sample of ...
