a) Explanation Given information: The concentration of chemical int eh contaminated water is 4%. After one month, 20% of the water is replaced with clean water. Calculation: Let A 0 be the initial percentage of the chemical present in the water. The percentage of chemical present in water at any time is A. So, we can write the equation for the concentration of the chemical as, A ( t ) = A 0 e k t Where, k is the constant and t is the time in month. The concentration of the chemical present in water after one month is 4 − 4 × 0.20 = 3.2 % . So, we have, when t = 0 , 0.32 = 4 e k ⋅ 1 e k = 0.32 4 e k = 0.08 Now, we have, A ( t ) = A 0 e k t A ( t ) = A 0 ( e k ) t A ( t ) = 4 ( 0 b) To determine The time after which concentration of contamination in water does not exceed the level of 0.01%.
