Answer
### The solution is unsaturated.
Explanation
## Step1: Identify the solute and solvent### The solute is
and the solvent is water (H
O).## Step2: Determine the amount of solute and solvent### There are 20 grams of
dissolved in 100 grams of water.## Step3: Determine saturation level at the given temperature### Check the solubility of
at
. The solubility of
at
is approximately 168 grams per 100 grams of water.## Step4: Compare the provided solute amount with the solubility data### Since 20 grams is much less than the 168 grams that can dissolve at
, the solution is not saturated.
