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.

Explanation:

Hello!

In this case, according to the reported solubility data for potassium nitrate at different temperatures on the attached picture, it is possible to bear out that about 170-180 grams of potassium nitrate are completely dissolved in 100 g; considering that the solubility is the maximum amount of a solute that can be dissolved in a solvent, in this case water.

Andrej [43]

Answer:

6. C3H2O

Explanation:

C= 12.0107; H= 1.00797; O=15.9994

We calculate:

C= 65.85/12.01=5.48

H= 4.91/1.00=4.91

O=29.24/16.00= 1.82

Later, we divide among the smaller quantity

C=5.48/1.82= 3.01

H=4.91/1.82= 2.70

O=1.82/1.82=1
