Concentration of a Solution
The concentration of a solution is defined as the amount of solute dissolved in a given amount of solvent. If we dissolved just a couple of crystals of table salt (NaCl) in water, we might not even be able to taste it. But if we dissolved a bunch of NaCl in the same amount of water (and you might be surprised how much will dissolve), it would taste very salty. On a relative scale, one solution is dilute and the other is concentrated. We'd like to be able to put this on some sort of numerical scale so that we could say just exactly how dilute or concentrated a solution is. Remember that the solute (usually a solid) is what's being dissolved in a solvent (usually a liquid)
