2) In this lab we will be working with solutions, which are homogenous mixtures of two or more substances. The solvent is the substance in greater amount (water in this experiment) and the solute is the substance in lesser amount. Concentration is the term used describe the amount of solute in a given amount of solution (solvent + solute). Concentration can be measured in many different units, grams solute per mL solution, % mass to volume (grams in 100 mL of solution), Molarity (moles solute per L solution) among others. Even though we have not learned about solutions in lecture, we know enough about units to understand and work with concentrations in the lab. Answer the following questions about concentrations. If you get stuck, visit Chapter 9 in a. If 15.0 g of sodium chloride (NaCl) are present in 250 mL of aqueous solution, what is the your textbook. concentration in the terms of mass/volume percent (g/100 mL)? b. What is the molarity (M or moles/L) of this solution? c. What happens to the molarity when the solution is diluted, i.e., 100 mL of water (solvent) is added?
