The definition of molarity is:
Molarity = moles of solute / total volume of solution in Liters
In this case, our solute is Sulfuric Acid. To solve this problem, let us assume a basis for calculation.
Let us say that,
Total mass of solution = 100 g
Therefore mass of H2SO4 = 20 g
The molar mass of H2SO4 = 98.079 g / mol
Calculating for number of moles of H2SO4:
number of moles = 20 g / (98.079 g / mol)
number of moles = 0.204 mol
Calculating for the volume of solution using the density:
total volume of solution = 100 g / (1.105 g / mL)
total volume of solution = 90.50 mL = 0.0905 L
Therefore the molarity is:
Molarity = 0.204 mol / 0.0905 L
Molarity = 2.2542 mol / L
Molarity = 2.25 M
