Question 18
H

A student mixes 50.0 cm3\mathrm{cm^{3}}cm3 of 0.200 mol dm−3\mathrm{mol\,dm^{-3}}moldm−3 barium chloride solution with 40.0 cm3\mathrm{cm^{3}}cm3 of 0.300 mol dm−3\mathrm{mol\,dm^{-3}}moldm−3 sodium sulfate solution.

BaCl2(aq)+Na2SO4(aq)→BaSO4(s)+2NaCl(aq)\mathrm{BaCl_{2}(aq) + Na_{2}SO_{4}(aq) \rightarrow BaSO_{4}(s) + 2NaCl(aq)}BaCl2​(aq)+Na2​SO4​(aq)→BaSO4​(s)+2NaCl(aq) Relative formula mass: BaSO4\mathrm{BaSO_{4}}BaSO4​ = 233

What is the maximum mass of barium sulfate precipitate that can form?
