Question

Every morning, Sarah prepares the same amount of coffee at the same temperature. Identify the coffee solution with the highest concentration. On Wednesday, Sarah poured sugar into her coffee until the sugar molecules were spread evenly throughout the entire cup of coffee. On Thursday, Sarah poured sugar into her coffee until undissolved sugar remained at the bottom of her coffee cup.

Answer 1

So if you are trying to find the coffee with the highest concentration of sugar, the cup that has the highest concentration of sugar is the cup that Sarah made on Thursday.

Since there were sugar molecules remaining at the bottom of her coffee cup, that means that the coffee solution was completely saturated with sugar - no more sugar was able to dissolve in the coffee.

Answer 2

Answer: On Thursday Sarah poured sugar into her coffee until undissolved sugar remained at the bottom of her coffee cup
