Densities of solutions of sodium hydroxide and water at 20 °c are given by the equation: p 1.003 +1.06wao where p is the density of the solution in g/cm (grams of solution per cm3 of solution) and wnaoh is the weight fraction of sodium hydroxide. the equation is valid for sodium hydroxide weight fractions less than or equal to 0.5. 100 liters of a solution that has a sodium hydroxide weight fraction of 0.5 is to be diluted with pure water until the weight fraction of naoh is equal to 0.2. what volume of water must be added and what will be the volume of the final mixture? express both volumes in liters. naoh
