A student wishes to prepare 1.000 g of silver chromate.
How many mL of .05000M silver nitrate solution should be added to 50.00 mL of .0700M potassium chromate solution assuming 100% yield
2AgNO3 + K2CrO4 ==> Ag2CrO4 + 2KNO3
mols K2CrO4 = M x L = ?
Convert to mols AgNO3. mols AgNO3 = 2*mols K2CrO4.
Then M AgNo3 = mols/L. You know mols and you M from the problem. Solve for L and convert to mL.
