This is a limiting reagent (LR) problem since amounts are given for BOTH reactants.
BaCl2 + Na2SO4 ==> BaSO4 + 2NaCl
mols BaCl2 = M x L = ?
mols Na2SO4 = M x L = ?
Since this is a 1:1 reaction, the LR is the one with the smaller mols.
That many mols BaSO4 will be formed.
Convert mols product to grams by g = mols x molar mass.
If 32.9mL of 0.170M BaCl2 are needed to react completely with 35.0mL of 0.160M Na2SO4 . How many grams of BaSO4 will be formed?
