The growth of Pseudomonas bacteria is modeled as a first-order process with K=0.035 min ^-1 at 37 degrees C. The initial Pseudomonas population density is 1.0 x 10^3 cells/L.
Enter your answers in scientific notations.
A) What is the population density after 4.0 h
B) What is the time required for the population to go from 1.0 x 10^3 to 3.0 x 10^3 cells/L?
