Answer:
392g sulfuric acid are produced
Explanation:
Based on the balanced equation:
2HCl + Na2SO4 → 2NaCl + H2SO4
2 moles of HCl produce 1 mole of sulfuric acid
To solve the problem we need to find the moles of sulfuric acid produced based on the chemical equation. Then, using its molar mass -Molar mass H2SO4 = 98g/mol- we can find the mass of sulfuric acid produced:
Moles sulfuric acid:
8mol HCl * (1mol H2SO4 / 2mol HCl) = 4 mol H2SO4
Mass sulfuric acid:
4mol H2SO4 * (98g / mol) =
392g sulfuric acid are produced
