Consider the reaction A ==> B. If the reaction is first-order in A with the initial concentration A being 6.048M, what is the concentration of A after 1.986 seconds if the rate constant is 0.483s-1?

Can someone explain how to do this? Thanks
ln(Ao/A) = kt
You know Ao, solve for A, you know k and you know t.
