One part per hundred is 10,000 parts per million, so 5.25% NaOCl is 5.25×104 ppm. Preparing a 200 ppm solution requires dilution by a factor of 200 ppm/ 5.25×104 ppm or 1/263. That means that the mass of Chlorox that must be diluted to 1000 mL is 1/263 of 1000 g ... For dilute solutions around room temperature,
