Answer:
About
40 g
Explanation:
You can determine how many grams of sodium chloride, commonly known as table salt, can be dissolved in
100 g
of water at
80
∘
C
by taking a look at its solubility graph.
A substance's solubility graph tells you how its solubility changes, let's say starting from room temperature, when temperature is either decreased or increased.As you can see, at room temperature sodium chloride has a solubility of approximately
35 g/100 g H
2
O
.
As temperature increases, its solubility increases as well. Notice, however, that it does not increase significantly. In fact, you can expect to be able to dissolve no more than
40 g
of sodium chloride per
100 g
of water at
80
∘
C
.
So, at
80
∘
C
, you will ahve an unsaturated solution if you dissolve less than
40 g
of sodium chloride, and a saturated solution if you dissolve about
40 g
of sodium chloride.
