Answer:
The question has some other details missing, but here are the details ;
Write a differential equation for the time (measured in minutes) evolution of:
a) The total mass (in kilograms) of the chemical in the pond dm/dt =
b) The concentration (in kg/liter) of the chemical in the pond: dc/d t=
c) The concentration (in grams/liter) of the chemical in the pond: dc/dt =
d) The concentration (in grams/liter) of the chemical in the pond, but with time measured in hours: dc/dt =
Step-by-step explanation:
The detailed steps from first principle and the solution of each differential equation is as shown in the attached file.
starting from Concentration = mass/volume ; mass = volume x concentration, and then find the differential of both sides to generate the solved differential equation.
