5. A stock solution of potassium nitrate, KNO3 has a concentration of 0.50 M. What volume of dilute potassium nitrate (0.10 M) can be formed with 80.0 mL of the concentrated solution?

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
