An unsaturated solution is made by completely dissolving 20.0 grams of NaNO3

in
100.0 grams of water at 20.0°C.
56 In the space in your answer booklet, show a correct numerical setup for calculating the
number of moles of NaNO3
(gram-formula mass = 85.0 grams per mole) used to make
this unsaturated solution. [1]
57 Determine the minimum mass of NaNO3
that must be added to this unsaturated
solution to make a saturated solution at 20.0°C. [1]
58 Identify one process that can be used to recover the NaNO3
from the unsaturated

The following are the answers to the questions presented:

a. Mols =
(20g)/(85g/m)

b. 88g – 20g = 68g

c. Evaporation of water / Boiling of water

I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.
