Answer:

7.235 mol of S are in the given sample

Explanation:

Number of mol calculated as follows:

Number of mol = amount in g / molar mass

Given that amount of sulfur = 232 grams.

Molar mass of sulfur = 32.065 g/ mol

Therefore the number of S is calculated as follows:

Number of mol = 232 grams/ 32.065 g/ mol

= 7.235 mol

7.235 mol of S are in the given sample

The Balance Chemical Equation is as follow,

                                  2 HCl + Pb(NO₃)₂     →    2 HNO₃ + PbCl₂

According to equation,

          331.2 g (1 mole) Pb(NO₃)₂ produces  =  278.1 g (1 mole) PbCl₂

So,

                 870 g of Pb(NO₃)₂ will produce  =  X g of PbCl₂

Solving for X,

                     X  =  (870 g × 278.1 g) ÷ 331.2 g

                     X  =  730.5 g of PbCl₂

Therefore,

               Theoretical Yield =  730.5 g

Also as given,

                Actual Yield =  650 g

So using following formula for percentage yield,

                        %age Yield  =  (Actual Yield / Theoretical Yield) × 100

Putting values,

                        %age Yield  =  (650 g / 730.5 g) × 100

                        %age Yield  =  88.98 %
