1M solution of H2SO4 means that 1 gram-molecular weight of H2SO4 is dissolved in 1 litre of water Molecular weight of H2SO4 is 2+32+64=98 which means that in 1M solution of H2SO4, 98 g of H2SO4 are dissolved in 1 litre of water whereas 1N solution of H2SO4, has 1gram equivalent weight of H2SO4 dissolved in 1 litre of water Now, the Equivalent wt of H2SO4 is 98/2=49 Therefore in 1N solution of H2SO4, 49 gram of H2SO4 are dissolved in 1 litre of water Comparing both the above solutions we can say that 1M solution of H2SO4 is more concentrated than 1N solution of H2SO4

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.
