The formaldehyde content of a pesticide preparation was

The formaldehyde content of a pesticide preparation was determined by weighing .3124g of liquid sample into a flask containing 50ml of .0996M NaOH and 50mL of 3%H2O2. On heating, the following reaction took place

OH- + HCHO-> HCOO- +2H2O

After cooling the excess base was titrated with 23.3mL of .0525M H2SO4. Calculate the percentage of HCHO( 30.026g/mol) in the sample
