The dilution equation obeys the law of conservation, i.e., the total number of moles of solute (the substance being dissolved) is conserved during the dilution process. V1 = volume about to be diluted. Reading comprehension . By dilution of a more concentrated solution (for example diluting 250mL of 2 NaCl to 500mL: C1V1 = C2V2) By preparing the solution from solid solute and water (500mL = 01/L = 0 NaCl58/mol = 29; measure out this solid NaCl and add water until 500mL is reached) If the wish of the family is to decline all medical treatments, the next step is __________________. The '2 ions / 1 formula unit' is the problem child.
