When aqueous solutions of K2SO4 and Pb(NO3)2 are combined, PbSO4 precipitates. Calculate the mass, in grams, of the PbSO4 produced when 1.98 mL of 0.165 M Pb(NO3)2 and 3.6 mL of 0.702 M K2SO4 are mixed. Calculate the mass to 3 significant figures.

Mass of produced is 99.1 g.

Explanation:

Chemical equation for the given reaction is as follows.

Moles of = Molarity × volume

                           =

                           = 0.3267 mol

Moles of

                            = 2.527 mol

As moles of is less. Hence, it is the limiting reactant.

We know that, molar mass of is 303.26 g/mol.

Then,

  0.3267 mol of =

                        = 99.075 g

or,                    = 99.1 g

Therefore, mass of produced is 99.1 g.

i don,t know so just answer mine

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
