Explanation: As you can see, potassium nitrate has s solubility of about
67 g / 100g H
. This means that at
, a saturated potassium nitrate solution will contain
of dissolved salt for every
You know that at this temperature, your solution contains
of potassium nitrate in
of water. This solution will be unsaturated because it contains less potassium nitrate than the maximum amount that can be dissolved.
In order to make a saturated solution, you must get the total mass of potassium nitrate to
, which means that you must add
mass of KNO
to be added
The answer is d.potassium
