5. Solving a chemistry problem

26. Half coagulation time of a mineral oil mist with a specific surface area of 1.5*107 m-1 and a concentration of 25 mg/l is 240 s. Calculate and plot the curve of change in the total number of particles during coagulation for the following time intervals: 60, 120 240 480 and 600 s. The density of the oil is 0.970 g/cm3.
