Answer:

(b) 26.6 days

Step-by-step explanation:

Half life, T = 4 days

initial amount, No = 100 mg

(a) The exponential function is given by

$N = No e^{-\lambda t}\\\\N = No e^{\frac{-0.693t}{T}}\\\\N = No e^{\frac{-0.693t}{4}}\\\\N = No e^{\frac{-0.17325t}{T}}\\\\$

where, N is the amount left.

(b) N = 1 mg

$N = No e^{\frac{-0.17325t}{4}}\\\\1 = 100 e^{\frac{-0.17325t}{4}}\\\\4.605 = 0.17325 t \\\\t=26.6 days$
