Question 5

Barium chloride solution mixed with sodium sulfate solution forms a precipitate of barium sulfate.

\text{BaCl}_2(\text{aq}) + \text{Na}_2\text{SO}_4(\text{aq}) \rightarrow \text{BaSO}_4(\text{s}) + 2\text{NaCl}(\text{aq})

In an experiment, the theoretical yield of barium sulfate for this reaction was 3.68 g. In the experiment, only 3.12 g of barium sulfate was obtained.

Calculate the percentage yield of barium sulfate in this experiment.

Give your answer to two significant figures.
