An experiment is done to determine concentration of ammonia y in a homemade glass cleaner formulation during storage. The concentration is given as a function of time, t by the following formula: dy dt = -10y At the initial time, t = 0; the ammonia concentration in the storage tank is 1 mg/L. Examine the concentration difference after 1 minutes between the analytical solution and Fourth Order Runge-Kutta Method with step size of h = 0.5 minutes. (25 marks)
