A solution with a molarity of 7.65 mol/L and a volume of solution of 0.690 L, contains 5.28 moles of solute.
<h3>What is molarity?</h3>
Molarity is the number of moles of solute per liter of solution.
A solution has a molarity (M) of 7.65 mol/L and a volume (V) of 0.690 L. We can calculate the number of moles of solute (n) using the following expression.
M = n / V
n = M × V = 7.65 mol/L × 0.690 L = 5.28 mol
A solution with a molarity of 7.65 mol/L and a volume of solution of 0.690 L, contains 5.28 moles of solute.

Answer:
When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue. When a solution containing dissolved solutes is heated, the solvent will evaporate.
Explanation:
. P.S. Evaporation to dryness cannot be use for solutions like sugar solution because the sugar will decompose upon heating.
Answer:
MgO- magnesium oxide
Cu(NO3)2- copper(11)nitrate
Li2CO3- lithium carbonate
In a saturated solution, extra solid X would remain solid, dissolve in an unsaturated solution, and crystallize in a supersaturated one.
A solution is said to be saturated when there is a maximum amount of solute present that has been dissolved in the solvent. As a result, the system is in an equilibrium between the dissolved and undissolved solutes: A solution is considered to be unsaturated if the solute concentration is less than the equilibrium solubility. A supersaturated solution is one that has more solute than is necessary to generate a saturated solution at a given temperature.
