Solution Concentration

Solution concentration refers to the amount of solute present in a given amount of solution. There are several ways to express solution concentration, including molarity, molality, and normality.

Molarity

Molarity is defined as the number of moles of solute per liter of solution. A 1 Molar solution of H2SO4 contains 1 mole of H2SO4 per liter of solution.

Molality

Molality is defined as the number of moles of solute per kilogram of solvent. A 1 molal solution of H2SO4 contains 1 mole of H2SO4 per kilogram of solvent.

Normality

Normality is defined as the number of equivalents of solute per liter of solution. An equivalent is a measure of the reactive capacity of a chemical species. For H2SO4, the number of equivalents is equal to the number of protons (hydrogen ions) that the acid can donate. A 1 normal solution of H2SO4 contains 1 equivalent of H2SO4 per liter of solution.

Answer Explanation

Of the three options given, only option A refers to molarity. Options B and C refer to molality and normality, respectively. Therefore, the correct answer is option A, which is a 1 Molar solution of H2SO4.

It is important to note that the concentration of a solution can affect its properties, such as its density, boiling point, and freezing point. In addition, different ways of expressing solution concentration can be used for different purposes, depending on the specific needs of the experiment or application.
