Answer:
to prepare 250 milliliters of a 0.5 Moeller sodium chloride solution using equipment common to a laboratory. The first thing I would do is figure out how many grams of sodium chloride would be present in 250 milliliters of a 2500.5 Moeller solution of sodium chloride. To do this, I'll take the mill leaders that I'm attempting to prepare converted to leaders. You've similarity to convert the leaders two moles of sodium chloride and then use the molar mass of sodium chloride to convert the mold. Sodium chloride, two grams sodium chloride. So I need to way out 7.305 brands If I would go to the balance measure out 7.35 7.305 Change that on the balance. 7.3 05 grams. I would then take that and place it into a 250 milliliters volumetric flask and then fill it up to the mark. There's always a mark on a volumetric flask that tells you the volume. Fill it up to the mark that is 250 mil. Leaders inverted several times. Make sure that the sodium chloride dissolves well, and then I would have 250 milliliters of a 2500.5 Moeller sodium chloride solution
