The cоncentrаtiоn оf sulfаte in а sample of wastewater is to be determined by using gravimetric analysis. To a 100.0-mL sample of the wastewater is added an excess of strontium nitrate, forming the insoluble strontium sulfate (183.7 g/mol) according to the balanced equation given below. The solid strontium sulfate is dried, and its mass is measured to be 0.3887 g. What was the concentration of sulfate in the original wastewater sample? SO42–(aq) + Sr(NO3)2(aq) → SrSO4(s) + 2NO3–(aq)
