Beaker B
Explicación
## Step 1The 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.## Step 2In 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.## Step 3Looking 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.
