What mass of precipitate is formed when 25.00 mL of 0.200 M BaCl₂ and 35.00 mL of 0.125 M Na₂SO₄ are mixed?

Question

Quizplus · Accepted Answer

The reaction between BaCl2 and Na2SO4 forms BaSO4 as a precipitate. The moles of BaCl2 are 0.005 mol and Na2SO4 are 0.004375 mol. BaSO4 is formed in a 1:1 ratio with the limiting reactant Na2SO4, producing 0.004375 mol of BaSO4. The molar mass of BaSO4 is 233.39 g/mol, so the mass of the precipitate is 0.004375 mol * 233.39 g/mol = 1.02 g.
