The solubility of sodium nitrate at 95º C in g/ 100 mL of water is 448.21.
<h3>Equation :</h3>
To calculate the solubility
Using formula,
Solubility = mass of the compound / mass of the solvent
Thus,
Known data is :
mass of the compound, sodium nitrate = 84.994 g/mol
mass of the solvent, water = 18.015 g/mol
C = 84.994 g/mol / 18.015 g/mol
C = 4.718 g/mol
By the temperature 95ºC
So,
C = 4.718 g/mol x 95ºC
C = 448.21 g/ 100 mL
<h3>Solubility :</h3>
The maximum amount of the sample that will dissolve in a given amount of solvent at a given temperature is referred to as its solubility. Different substances have very different solubilities, which is a characteristic of a particular solute-solvent combination.

One instance of forgoing lab safety would be a simple drop of a chemical into a test tube, and not wearing protective eye gear. Although it seems irrelevant to put on the goggles just for this matter, it is ultimately the safest option to do so in order to remain unharmed.

Answer:
A solution is a heterogeneous mixture
Explanation:
This statement that a solution is a heterogeneous mixture is completely and totally wrong.
A solution is a homogeneous mixture.
Homogeneous mixtures have their constituents existing in just one phase.
- It is a homogeneous mixture of solutes and solvents.
- In a solution, the solutes particles are distributed uniformly in the solvent.
- The solute is the substance that is dissolved to make the solution.
- Solutes are usually present in a small amount than the solvent.
- The solvent acts as the dispersing medium which allows the solute to go into the solution.
- The solute can be solid, liquid or gas.
