The grams of solute are required.
The mass of solute is 3.5 g
c = Molarity = 0.1 M
M = Molar mass = 350 g/mol
V = Volume of solution = 100 mL = 0.1 L
n = Number of moles
m = Mass of solute
Molarity is given by

A saturated solution is one that contains all of the solute that can possibly dissolve in it. The most sodium chloride that may dissolve in of water at
°C is
. Past that point, adding more
won't cause it to dissolve because the solution is already saturated.
The solution reaches a point when it is saturated. This indicates that if you add more of the substance, it will stop dissolving and instead stay solid. The amount depends on how the solvent and solute interact molecularly.

Answer:
(4)KBr(aq)
Explanation:
A mixture is an impure substance made up of two or more substances that are joined together. Their composition is indefinite and not easily represented by a simple chemical formula.
KBr is a mixture because it made up of an aqueous solution of KBr. This suggests that the substance KBr is placed inside water.
Here, we have two states of matter which is the solid and the liquid coming together.
As with both mixtures, they can be separated by physical means, KBr aqueous solution can also be done this way.
