46. Solving a chemistry problem

365. River water contains colloidal particles of organic impurities. To use it for the purposes of the plant, coagulation is preliminarily carried out, and then it is settled in special settling tanks to remove sludge. Calculate the NaCl consumption (kg per day) if the water consumption at the enterprise is 300,000 m^3 /day, and the NaCl coagulation threshold is 52 mol/m^3.
