Reaction Stoichiometry Example 1.10 p. 15 Reaction: O H PO Ba PO H OH Ba 2 2 4 3 4 3 2 6 ) ( 2 ) ( 3 + + Question: What mass of barium phosphate (BP) is produced by complete reaction of 16.8 g of barium hydroxide (BH). Method: Use the fact that the coefficients provide mol ratios between various species allowing us to relate mols of one to mols of another. Step 1: Convert mass info regarding barium hydroxide to mol info.
