Concentration and Solubility Revision
Which two solutions have the same concentration? Which two solutions have the same concentration? Concentration = mass of solute (g) Solution A 4/25= 0.16g/ml Solution B 4/50=0.08g/ml volume of total solution (L) Solution C 2/25= 0.08g/ml Solution D 8/50= 0.16g/ml
15 g of sodium chloride was dissolved in water. The total volume of the sodium chloride solution was 0.75 L. What is the mass concentration of the sodium chloride solution in g/L? Concentration = mass of solute (g) volume of total solution (L) =15 g/0.75 liters =20 g/L
Solution A has more purple particles per milliliter. So, Solution A has a higher concentration of purple particles.
