A 1.009-g mixture of the solid salts Na2SO4 (molar mass=142.04g/mol) and Pb(NO3)2 (molar mass=331.20g/mol). The precipitate was filtered and dried, and it mass was determined to be 0.471 g. The limiting reactant was determined to be Na2SO4.

a. write the molecular form of the equation for the reaction?

b. write the net ionic equation for the reaction?

c. How many moles and grams of Na2SO4 are in the reaction mixture?

d. How many moles and grams of Pb(NO3)2 reacted in the reaction mixture?

e. what is the percent by mass of each salt in the mixture?
