If 3.45 moles of table salt react with 98.6 mL of sulfuric acid, what is the limiting reactant if the density of sulfuric acid is 1.13 g/mL? How much sodium sulface would you produce?

Write down the balanced chemical equation for the reaction taking place.
Work out the number of moles of sulfuric acid used.
From your equation, find the mole ratio between the reactants and use that to determine the limiting reactant.
When you got the limiting reactant, make another mole ratio, this time between the limiting reactant and sodium sulfate.
From there, work out the number of moles of sodium sulfate produced.
