To prepare olives for consumption and remove their bitterness, powdered soda (sodium hydroxide, NaOH) is usually used in the industry, which is added to the water in which the olives are found (this method should not be used at home if we had olive trees because soda is highly corrosive and very dangerous, in this case we should use table salt). Normally 1 kilogram of soda is added for every 3 liters of water (weighing 3 kg, remember that the density of water is 1 g/mL). Thus, 4 kg of solution were obtained, and the density of this solution was determined experimentally to be 1.25 g/mL. a) Calculate what volume of solution is obtained. (Remember that d = m/V). b) What will be the concentration of that solution expressed in grams of solute dissolved in each liter of solution? c) What will be the concentration expressed in % by mass (or weight)? • If we separate a ladle (100 mL) of that solution. d) What will be the concentration of soda in the liquid in the ladle? e) How many grams of soda will be in the liquid in that ladle?
