Chemistry practice q

Hello, could explain how to solve this type of questions?

6g of Mg24 is added to a solution containing 30g of dissolved sulphuric acid (H2SO4). Which of the following statements are true?
Relative Atomic Masses: S = 32, Mg = 24, O = 16, H = 1

  1. In this reaction, the magnesium is the limiting reagent
  2. In this reaction, sulphuric acid is the limiting reagent
  3. The mass of salt produced equals the original mass of sulphuric acid

6g og Mg corresponds to 0.25 mol.
30g of H2SO4 corresponds to less than 0.33 mol.
The stoichiometry of this reaction reveals a 1:1 mol interaction between the two reactants.

So, the reactant which exist in less amount and therefore consumed first, will be the limiting factor of this reaction.

Option 3 is not correct due to the stoichiometry of the reaction and the law of mass conservation which in this case has not considered the mass of the liberated hydrogen gas together with the produced salt.

thank you very much!
