Let's solve this step-by-step.
1. Understand the initial conditions:
- The student starts with 500 milliliters (ml) of a 2.5 M (molar) sugar solution called Mountain Dew.
2. Volume Poured:
- The student pours out 25 ml into each of the three separate containers.
3. Number of containers:
- There are three containers.
4. Total Volume Poured:
- The student pours out a total of 25 ml per container × 3 containers = 75 ml.
5. Molarity Consideration:
- The molarity (concentration) of the solution in a container is a measure of the amount of solute (sugar) per unit volume of solution.
Now, when dealing with molarity and concentration, it is important to note that the molarity is a characteristic of the solution; it doesn't change unless the composition of the solution changes (for example, by adding more solvent or solute). Here, the student is simply transferring a portion of the same solution to different containers. We are not adding more sugar or more water; we are just distributing the existing solution.
6. Conclusion for Molarity:
- Since the molarity (2.5 M) of the original Mountain Dew solution is consistent throughout, and we are merely transferring portions of this homogeneous solution to other containers, the molarity of the solution in each of the three containers will be the same as the original molarity.
Thus, the molarity of the sugar in each of the three containers is 2.5 M.
