Molarity determines the molar concentration of the solute dissolved in the solution. Mass and volume should be measured for the estimation of the molarity.
<h3>What is molarity?</h3>
Molarity is the mass of the solute present in the litre of solution. It is also called molar concentration as it estimates the concentration of the compounds.
The unit of molarity is mol/L and can be given by the formula:
Therefore, for the formation of a 2M potassium nitrate solution, the volume of the solution and mass of the solute is required.

Explanation:
Answer:
C. transition elements
Explanation:
Transition elements are groups of metallic elements that have partially filled d orbitals. They occupy the d-block of the periodic table (Group 3-12). Examples of elements that fall under this category are Nickel (Ni), Cobalt (Co), Copper (Cu), Zinc (Zn) etc. Transition metals have outstanding properties that distinguishes them from other elements.
One of these properties is their ability to form colored compounds due to their unfilled d electron shells. They form ions that are usually colored in solid compounds and in solution.
The most common way of preventing bumping is by adding one or two boiling chips to the reaction vessel. However, these alone may not prevent bumping and for this reason it is advisable to boil liquids in a boiling tube, a boiling flask, or an Erlenmeyer flask.
