Question:

In a coulometric Karl Fischer water analysis, 25.00 mL of pure “dry” methanol required 4.23 C to generate enough I2 to react with the residual H2O in the methanol. A suspension of 0.847 6 g of finely ground polymeric material in 25.00 mL of the same “dry” methanol required 63.16 C. Find the weight percent of H2O in the polymer.
