(Hint: Use the density and molar mass of water.) What happens to the concentration of water when a solute is dissolved in it? (1000 g/L) / 18.0 g/mol = 55.6 mol/L. The concentration of water decreases as a the concentration of a solute increases because the solute occupies some of the volume and the water molecules are pushed apart. 4

Molar conductivity is the conducting power of cell the ions produced by one mol of an electrolyte. It is given by = Variation of and with concentration. Conductivity decreases with dilution. Because the number of ions per unit volume that carry the current in a solution decreases. Molar conductivity increases with decrease in concentration.

When you are calculating the concentration of a solution, you must do so by calculating the number of moles of solute dissolved into the total volume of solution. Example 1: Molar mass of salt (NaCl) is 58.5 g/mol, so if you dissolve 58.5g of salt in enough water to make 1.00 liter of solution, you have one mole of solute dissolved per liter of ...
