In an experiment, a student added a specified amount of sodium chloride to 10 Lo in each beaker is listed below: Beaker A: 2.5 of NaCl in 10 L of water Beaker B: 0.7 go NaCl in 10 L of water Beaker C: 15.6 g of NaCl in 10 L of water Beaker D: 41.3 g of NaCl in 10 Lot water Which beaker contains the LEAST concentrated solution? Beaker A Beaker B Beaker C Beaker D

## Step 1<br />The concentration of a solution is determined by the amount of solute (in this case, sodium chloride or NaCl) dissolved in a certain amount of solvent (in this case, water). The more solute there is in a given amount of solvent, the more concentrated the solution is.<br /><br />## Step 2<br />In this experiment, the amount of sodium chloride (NaCl) is given in grams for each beaker. The beaker with the least amount of sodium chloride will have the least concentrated solution.<br /><br />## Step 3<br />Looking at the given amounts of sodium chloride for each beaker, we can see that Beaker B has the least amount of sodium chloride, which is 0.7 grams.
