(potassium nitrate) is least soluble in water at 20°c.
<u>Explanation:</u>
The deciding element for the outcome is the dissolvability of the substance, which is characterized as the greatest conceivable centralization of the solute. The solvency rules help figure out which substances are solvent, and to what degree. Dissolvability demonstrates the greatest measure of a substance that can be broken down in a dissolvable at a given temperature. Such an answer is called soaked. Separation of the mass of the compound by the mass of the dissolvable and afterward duplicate by 100 g to figure.
Mass is the measure of the quantity of the substance present in the sample containing a compound or molecule. The mass of sucrose in the sample is 171 g.
<h3>What is mass?</h3>
The mass of the compound in the sample is the product of the number of moles of the substance and the molar mass of the compound.
Given,
The molar mass of the sucrose compound = 342.3 g/mol
Number of moles of sucrose = 0.500 moles
Mass of sucrose is calculated as:
Therefore, option A. 171 gm is the mass of sucrose.
