To calculate the mass concentration, moles of H2SO4 used, and density of the solution, you'll need to use the given information about the volume of the solution and the concentration of H2SO4.

(a) Mass Concentration:
Mass concentration (also known as the molarity or molar concentration) is defined as the amount of solute (in moles) divided by the volume of the solution (in liters).

Given:
Concentration of H2SO4 = 0.012 mol/dm³
Volume of solution = 2 L

To calculate the mass concentration, first convert the given volume from liters to cubic decimeters (dm³):
Volume of solution = 2 L = 2 dm³

Now, use the formula for mass concentration:
Mass concentration (in mol/dm³) = Amount of solute (in moles) / Volume of solution (in dm³)

Mass concentration = 0.012 mol/dm³

(b) Moles of H2SO4 used:
Given:
Concentration of H2SO4 = 0.012 mol/dm³
Volume of solution = 2 L

To calculate the moles of H2SO4 used, multiply the concentration by the volume of the solution:
Moles of H2SO4 = Concentration of H2SO4 × Volume of solution

Moles of H2SO4 = 0.012 mol/dm³ × 2 dm³

(c) Density of the solution:
Density is defined as mass per unit volume. To calculate the density, you'll need both the mass and the volume of the solution.

To find the mass of the solution, multiply the mass concentration by the volume:
Mass of solution = Mass concentration × Volume of solution

Given:
Mass concentration = 0.012 mol/dm³
Volume of solution = 2 L

First, convert the volume from liters to cubic decimeters (dm³):
Volume of solution = 2 L = 2 dm³

Density (in g/dm³) = Mass of solution (in grams) / Volume of solution (in dm³)

Note that the mass of the solution is equal to the mass of the solute (H2SO4) in this case, since there is no solvent mentioned. So:

Density of solution = Mass concentration × Volume of solution / Volume of solution
Density of solution = Mass concentration

Finally, the density of the solution is equal to the mass concentration:

Density of solution = 0.012 mol/dm³

Keep in mind that these calculations assume that the volume of the solution is the same as the volume of the solute (H2SO4), as no solvent is mentioned in the question.
