The formaldehyde content of a pesticide preparation was determined by

weighing 0.2985 g of the liquid sample into a flask containing 50.0 mL of 0.0959 M NaOH and 50 mL of

3% H2O2. Upon heating, the following reaction took place:

OH2 + HCHO + H2O2 → HCOO2 + 2H2O

After cooling, the excess base was titrated with 22.71 mL of 0.053700 M H2SO4. Calculate the percentage

of HCHO (30.026 g/mol) in the sample.
