###### FREE Expert Solution

We’re being asked to calculate the amount of A remaining after 8 half-lives if we start with 0.882 M A.

Recall that half-life is the time needed for the amount of a reactant to decrease by 50% or one-half. One way to determine the amount remaining after x half-lives is: where [A]t = concentration after x half-lives, [A]0 = initial concentration and x = number of half-lives. ###### Problem Details
