126. Solving a chemistry problem

Alkaline hydrolysis of ethyl acetate is a second-order reaction with a rate constant k = 0.084 L*mol-1*s-1 at 25°C. Taken 1 l of 0.05 M solution of ethyl acetate. What is the time required for the formation of 1.15 g of ethanol at the initial concentration of alkali:
a) [OH -]0 = 0.05 M;
b) [OH-]0 = 0.1 M?
